Golf IV R32 :: Front Brakes Locking Up


Feb 22, 2015

What would cause this? The brakes work fine until you get into that range of brake pressure in which the abs wants to kick in. The brakes then lock up(may be only front driver), the pedal sinks to the floor, and don't disengage until the car is at a complete stop. It does this with esp on or off.

The previous owner changed a front wheel sensor and bled the brakes. The abs module fuse under the battery cover was melted but not blown.

VCDS shows no codes. I did not do output test on pump, didn't have my laptop with me.

Abs pump bad?
Mc?
Servo?
Caliper?
Brake line?

I bought this car 2 weeks ago and the previous owner failed to let me know about the problem and it happened to me a mile down the road after purchasing the car. I started to notice a lot more because of the rain and snow recently. It's definitely an uneasy feeling. I really don't wanna drive the car till it's sorted.

Camry :: Front Right Brakes Gradually Start Locking Up When Driving

Replaced all components of front right braking system. Calipers rotor pads and hoses. Still, every other day or so the front right brakes gradually start locking up within minutes of driving.

I just bought car. I am stuck with this problem now. Only thing left i'm told is replacement of abs module.

Can you just bypass a faulty abs module instead of replacement?

Subaru - Forester :: 2003 - Front Brakes Locking Up Especially On Hot Days

I have a 2003 Forester, recently noticed the front brakes locking up, especially on hot days. Completely immobilized car, to get going again I would have to wait for them to cool and/or cool them with water if pads smoking from trying to drive with brakes engaged, and tap on calipers and master cylinder to allow pads to release. Problem got worse as it got hotter out, due to job I rarely drive car and didn't get in for service yet. Last time pads burned a whole lot and braking felt odd (less pressure and uneven like rotors were messed up or pads burned up).

Took it into brake place, they had never seen before. When they inspected, discs were in bad shape with one cracked, but I don't think that was original problem, just caused by driving with them hot. Shop at first said fluid seemed clean but I left and later they said it was contaminated but I don't trust them. Shop solution is replace everything: calipers, pads, hoses, flush system, and replace ABS (the most expensive part I am hoping isn't actually necessary). I don't trust shop for several reasons including because they admitted having never seen this and seemed content to take maximum amount of money just to replace everything without knowing what actual problem was.

Toyota - Camry - Struts :: Front Of Car A Little Wiggly / Brakes Locking Up

My husband noticed that our 2001 Camry was driving strange. He thought it was a problem with the brakes locking up. When I drove it, I felt like the front of the car was a little wiggly and thought we might need an alignment. When we took it in, they said that the brakes are okay, but that the front struts are "soft." They said that the front struts need to be replaced, which includes an alignment, and we should replace the rear struts at the same time. They said we should get new tires at the same time.

I've been trying to research it some, and we don't have a lot of the problems associated with bad struts. We haven't noticed any bouncing or anything like that. I think they are honest mechanics, but my husband doesn't trust them. We don't have enough money to get all that work done right now, so my question is, can we wait until we notice bouncing or the tires get worse to have the work done? (We would be trying to save up the money in the meantime.) Or, can we just take care of the front struts and wait on the tires and rear struts? Should we just get a second opinion? (The car does have 145,000 miles on it, and I've never had the struts replaced. I bought it with about 65,000 miles on it.)

Ford Brakes/Suspension :: Hub Locking - Bang From Front End When Engage 4WD

I have been having hub locking trouble and finally located a bad vacuum hose. Hose has been replaced. Now when I engage the 4WD and apply a little power, I get a terrible bang out of the front end, then the truck moves on. Sometimes there is a second bang, sometimes not. The chain appears tight in the transfer case and the ujoints look ok. I have turned the wheels with hubs locked one at a time and the joints are free.

Ford Brakes/Suspension :: 2008 F350 - Front Left Wheel Locking Up Intermittently

2008 F-350 wheel will lock for no reason. I think the Hydroboost has a hair line crack it and when the temp and pressure reach a certain number then it sends brake fluid threw the crack to the caliper? I also heard it could be in the ABS because its locking just one wheel?

Golf IV R32 :: Wheels Locking Up Under At-the-limit Driving / Brakes Malfunction

Today I had a wonderful experience at the morning session of the Auto X school at Waterfest 19. It was my first autocross experience and, man, it was a blast. I couldn't believe the car I've been daily driving for three years has so much untapped potential!

Anyway, I had a bit of a technical issue that was holding me back. I got my first two runs in with the instructor on board; I was slow but had no issue. Then, the instructor took the wheel to show me how it was done and ended up spinning the car out on a section of the course with back to back 90's turns, turn #2 having a reducing radius. It felt as if the brakes just locked up and the back end just came all the way around. Once I got back in and had more of a grasp of the car's ability, I experience the same issue and had a few spin outs of my own, in glorious clouds of white smoke.

The feeling is like the car locks the brakes, the brake pedal travels further to the floor, and the throttle is disabled until the car settles again. It even happened once or twice without pressing the brake at all; just engine braking and hard turning in, the brakes locked with no interaction with the brake pedal.

I've been able to duplicate the experience by "panic braking" in the straight line. When the car begins to skid, letting off the pedal will not disengage the brakes and the throttle will be deactivated until the car settles.

What would cause this? ESP was off, but do our cars have a yaw sensor or some system that will still apply the brakes when the car is at its limit? I searched but didn't find much. The car is on stock suspension.

Ford Brakes/Suspension :: 1999 F250 V10 - Transmission Not Shifting Correctly / Brakes Locking Up

I have a 1999 f250 super duty, that was wrecked a few months ago. I have put the truck back together with the mechanic. The front drivers side was wrecked. The power steering fluid tank was cracked and had to be replaced. Also had problems with a box behind the drivers headlight? I did hard wire it together and it fixed the problems i was having the the speedometer and the transmission not shifting correctly.

Everything is put back together now but I drove it today and the brakes locked down after driving it a few miles? Had to push the truck hard to get it back to my house, a mile or so. If i let off the gas it would come to a quick stop. It is ALL four brakes locking up. If it sits for awhile they unlock but will lock up again after driving. The truck is lifted and the ABS light has come on.

It was not on before but i am pretty sure the ABS is disabled on the truck. the wires are hanging down by each tire. This is how they truck was when i bought it. Not sure what is causing the brakes to lock up.

Prius (Gen 3) :: Brakes Locking - Tires Squeal

I have had my 2011 model III for a month, and today I had to brake rather abruptly. I heard my tires squeal! Is this normal? I have owned at least two other vehicles with ABS, and I recall the pulsing of the pedal, but not tire squeal.

Saturn - Vue :: 2006 - Rear Brakes Are Locking Up

I have a 2006 Saturn Vue that has an intermittent problem. After commuting for 50 miles and parking for the day, when I leave to go home by pulling forward out of the parking space, there is a loud metallic clang and the left rear wheel locks. When I step on the brakes to stop the car stops, but the rear wheel stays locked. When I press the brake pedal all the way down about half way down there is a difference in pressure on the pedal and the rear wheel releases. This will repeat up to three times. Has also happened after the 50 mile drive and stopped at store for 20 minutes. Will not repeat every time, and of course not when there is a mechanic is anywhere near the vehicle.

Toyota - Camry :: 1996 - All Four Brakes Keep Locking Up

I have a 1996 Toyota Camry, I was having a noise from right rear and every now and then the car would start slowing down like I was braking. I replaced all four calipers, rotors and the pads, then bled the whole system. The noise went away, but the car still seems to engage the brakes, but only after a few minutes of driving, but then it goes away.

I thought it was a single brake line, but after not driving it for a week, yesterday I was driving it and after about 20 minutes it started again, when I pulled over all for wheels were smoking, after allowing it to sit for a few minutes, I was able to drive home 30 miles without it happening again. Would this happen with just one line bad, as someone suggested, or is this an issue with the master cylinder, bad brake fuild or something else?

Ford F-150 (2004-2008) :: Brakes Locking Up - Fix?

my front brakes have been locking up here recently. I think it my be due to a blockage in the resovior. I had taken it apart upon the first spell of it locking up, had my buddy press the brake pedal a few times with the lines from the res disconnected and it seemed to be be a little clogged at first and then freed up once it was stepped on hard a few times. So i reassembled the system and bled the brakes out and it seemed to be fine for about 70 miles or so. Then out of no where it started locking up once again.

Ford F-150 - 1997-2003 :: Rear Drum Brakes Locking Up

I'm having a problem with my rear drum brakes locking up when I press the brake pedal. I've had this problem before, but ignored it because it wasn't too bad. It would just release after taking my foot off the brake pedal.

1998 F-150 XLT supercab 4x4 front discs, rear drums 4.6L v8 175k miles

I cleaned my master cylinder and bled all brake lines so they have fresh fluid. Now that my brakes work way better, my rears just lock up. I put new brake cylinders on, still locking up. I went to a junkyard today and replaced the proportional check valve, brakes still locking up.

Could I maybe have did something wrong when cleaning the master cylinder? I'm sure I put it back together correctly. Anything else i should look at? bad lines maybe?

Ford Ranger / B-Series :: 1998 - Rear Brakes Locking Up Very Easily

I just had new shoes, hardware, wheel cylinders, drums, leaf springs, rear shocks, and shackles put on. The brakes were done about 4 or 5 months ago and the springs and shocks just a few weeks ago. The rear brakes were locking up after I had the work done, but I thought they were just too tight. I loosened them a little but it only worked a little.

Now it's starting to lock up pretty much every time I apply the brakes. The ABS kicks on and the rear tires skid. I took the drums off today and didn't see any leakage or anything out of the ordinary. They weren't too tight and I readjusted them but they weren't out of adjustment much if at all. I looked at the Ford symptom chart and it says for brakes that lock up easily there could be sticking or binding components. I didn't see any. Then it says check parking brake components.

Now I see they didn't hook up the equalizer bracket that goes to the front leaf spring hanger when they changed my springs so I assume thats why my parking brake pedal goes to the floor. Then it says check the shoes and linings, which are fine. The last thing it says is to check the fluid control valve. Which I'm guessing is the prop valve.

The only way to check it according to Ford is swap it for a known working valve. One person told me that it could actually be a bad brake booster check valve. Is that possible? Anything else that's common? It's got 272,000 miles on the frame but everything's been changed that typically wears out at least once.
