Ford F-150 - 1997-2003 :: 1998 - New Front Calipers / Brakes Barely Functioning
Jun 9, 2013
I just bought a 1998 F150 2wd with the 4.6L(no ABS) to be my beater home depot truck. The brakes barely functioned, so I replaced the front bearings, rotors, pads, and calipers. I bled the brakes exactly like I normally do. When I tried to move the truck, the rear tires spun with the front completely locked(also discovered the right rear line had a hole and crimped the line for a moment, but it was the tire that was spinning).
I searched and many people said that bad rubber lines cause the calipers to lockup. I loosened the bleed valves and the fronts were still locked(jacked up the truck and used a breaker bar on lug nuts trying to rotate each tire). I am guessing that it has to be master cylinder or the steel lines. Any tests I could do to narrow down this issue further?

I have a 99 150 4 wheel drive..5.4 ..auto...110.000 mile.....notice when driving in town in hot weather....when you are on and off the brake petal a lot....stop and go..etc.....the truck starts to hop or bounce....some....I got out ..and notice the right or passenger side front brake seems a lot hotter than the drivers side......but ...when it does that....the steering wheel doesn't pull to one side...when changing pads before ..notice no one side worse for ware than other...thinking it must be sticking brake calipers....they don't do this say on interstate driving even when on and off the petal some...

I have a 2005 F250 & both front calipers are locking up. I have replaced the front pads, no change, my mechanic installed a new master cylinder. No lockup for about two weeks until today. Front calibers are locking up again.

I have a 1998 f150 4x4 4.6 triton V8 regular cab, I would like to ditch the rear drum brakes in favor of disk brakes. is this an easy bolt on project? I do know that 2003 f150's had rear disk brakes and was wondering if i bought those parts if the procedure would be fairly easy. I know i would have to take a check valve out of the master cylinder to gain pressure to the rear.

This is on my 98 F-150 4x4 with the 5.4 and 4R100. What happens is when I put the truck in reverse and get on and off the brakes, every time I do so a relay clicks. It sounds like it's right up behind the instrument cluster.
I stuck my hand back there and can feel the click resonating in the metal brackets, but I can't figure out where it's coming from. It's never done this before and I'm worried something may fail at an inopportune time.
What this may be? It's a really loud click too and only does this in reverse. Park, drive, neutral etc. are all fine. The odd thing is when I hear the click everything still works as normal, parking lights, brake lights, reverse lights.

If I even fart in my truck, there is a jingling underneath. I know my ball bearings need to be replaced. But, what the noise is. It sound like loose change in my pocket. I can't describe it any better.

I'm not too familiar with these trucks, but I've been working on my buddies 1999 e350 ford van.
The other day we were going out kayaking, and the brakes locked up, we were able to drive it home, but it was obvious the brakes were holding the truck back. decided to check it out today, found one front and one rear caliper were sticking, the dual piston calipers only had one working, which I believed to be causing the pads to get pressed together crooked, and caused them to "lock up" or get stuck.
anyways, got the new calipers on and no more sticking, so I bled the brakes started in the front and went all the way to the back, did every caliper. brakes feel firm with the vehicle off, but instantly when the van is started, the pedal goes to the floor. it still stops okay, but the pedal feel is not nearly where it should be.
I got all of the air out of the system, but the abs light is on, and has been for a while. I'm wondering if there is something else that needs to be bled in the abs? someone was telling me about bleeding the abs motor?

I have a 1998 F150 with a 4.6 engine and is a 4x4 now the other day when I was backing out of the garage I heard a clunk noise and it seems like it is coming from the right front, so I tried it going forward it made the same noise but not as bad. There is no road noise and all the u joints are good and tight, the noise was when I gave it a little gas. My question is the front cv u joint would this make the noise? And what about the hub? What is the proper why to check the CV joint and the hub? The noise was when I was in 2 wheel drive.

My t case will engage in 4 high and 4 low. so i know the switch and motor works because it go all the way to 4 low and i can feel the lower gears. BUT the front drive shaft is not turning because i know that the front diff is engaging just fine cus one I just fixed it and because when i put it in 4x4 the front drive shaft is locked in but when i take it out the drive shaft moves freely when i turn it by hand. But when I test it in gravel or mud the front wheels still ain't turning. So its gota be the t case. But what are the part that may be broken in the t case and if I can fix it wile its still on the truck.

1998 F250 ld 5.4 4X4 4wabs. The front rotor was seized on THOROUGHLY bearing split apart (outer bearing and bearing "core" still attached to rotor, outer race inner bearing and sleeve still in steering knuckle), the bearing was fine fine until i tried to remove the rotor, any chance it can be pressed back together and saved?

What would cause my front disc brakes not to work. I have replaced the master cylinder, calipers, hoses and pads. Backs work fine but I can not get good pressure to the front. 1993 f150 5.0 ..

I had both front brakes lock up on me the other day and burnt the shoes out so I replaced the pads and installed new calipers and flex lines. I also went ahead and replaced the rear shoes and both wheel cylinders since this truck had been sitting up for the past few years I figured why not. I flushed the system out but I can not get all the air out of the right rear wheel cylinder. My question is could the new wheel cylinder be bad? The new left cylinder blew out when I first started bleeding the right side. I could not get any pressure at all and I looked over and seen fluid pouring out the left side. I put the old one back on only due to time restraints. Should I replace the right side again as well? I have used up 4 1/2 bottles of 3e2 oz brake fluid and still have air in that side.

So when I got this truck everything on the brakes were messed up. So long story short I got a new master cylinder new pads and all lines are bled. Now this hole time my ABS light has been on so I looked at all the sensors and i found one connector that goes to the rear axle but it has no where to plug into. But I also found some writing on the axle which tells me that is a different axle and may not have had ABS set up. But I am not sure. Now the problem I am having is when I hit the breaks i don't have much bite but if i push on them harder the rear will lock up and the front brakes are biting just a little like 50% power. So how can I get more stopping power to the front pads ? And if its that unconnected sensor is there anyway i can loop in out of the system ?.

I have a 99 f150 4x4 that has done this twice, once last year and once this year during hot (90+) weather. I'll notice the vehicle seems like it doesn't want to go. Park overnight and it will work ok. Last time it happened the other day I stopped at wally world and both front wheels were real hot and I could smell the brakes. Came out hour later and when I pushed the brake pedal to put it in gear the pedal went to the floor.
Pumped up pedal and drove off but truck would barely move, drove 10 mph to a buddy of mines shop and it sat overnight and worked perfect the next day. He inspected everything and seems to think it might be the abs control unit. He noticed a small amount of fluid had come out of the unit and dripped on the ground. Also no abs light or brake light has ever come on

I have a 1998 F-150 V8 4.6L. Currently has about 83000 miles. I have had this problem twice now. When I park on an incline with the front up hill the engine will not start. It will crank like it is trying to start, but it sounds like its not getting enough fuel. Both times my tank has been nearly full or 3/4 full. Just put on a new fuel filter and the old one was still clean. ( I could blow through it with ease). I think it is the fuel pump.

Bought a high mileage 99 f150 4x4 yesterday. In the process of cleaning her up, the water hose hit the disc brakes on the drivers side and it was hotter than a BBQ grill! Ok, immediately I thought this isn't good. Jacked her up and pulled the caliper. Pads were almost gone so replaced them with a new set, went for a drive. Now the damn things were smoking so bad I thought they were gonna catch fire! Sticky caliper , right? Stopped and got one then realized that the passenger side started doing it too.
Another trip for the other caliper and new pads because these were toast. I mean just burnt to hell. Before I started working on the truck again, I checked on here and I'll be darned if I didn't find out that the old brake hoses might be acting like a check valve because of rust and deterioration. Got a set of brakes hoses too. Put everything on this morning and works like a charm.
1999 4.6 XL
Passenger side done

Going down a steep loose gravel drive way, going maybe 5 miles per hour. About 50 feet before the stop sign we lightly applied the brakes and the front right wheel completely locked up. If we didn't turn into the grass we would of stopped in the middle of the busy street. We picked up speed when we applied the brakes, like we were on ice. When I got out, I could see the one long brake mark in the driveway. This happened on a paved road about 6 months ago, it had some loose gravel at the stop sign. I couldn't tell which wheel locked up at the time. This happened on snow in December to, twice. Since the ABS light never came on. Brake pads and rotors needed replacing about 9 months ago. Tires have been rotated, no change. Not sure what it could be. I disconnected the Abs fuse for now.

I have a 2001 f150 4x4 5.4 Liter 72000 miles. There is a rubbing sound that is only audible when the brakes are applied. And only when applied with light pressure. The noise will continue intermittently until you come to a complete stop. If the brake is applied aggressively there is no sound at all. I am not sure if it is a brake issue or some thing in the front end that is flexing when slowing down.

It's a farm truck, lumber getter trailer puller. Not driven often, after sitting for awhile the brakes seem to be pulsing in front like antilock, as if braking on ice. I checked both front caliper springs or plunger slides and they are free not froze up.

I have a 98 F250LD, its a Lariat, so everything electric/auto. Shift on the Fly 4x4, 5.4, 188K, Factory rear air suspension. Typical Minnesota rust. Anyway, I just noticed in the last 75 miles or so, a drive-line vibration. There is nothing until 39 MPH. Then from 39-41 MPH there is a decent vibration. Stops until 50, then from 50 MPH up it is a steady vibration. I have already changed the u-joints in the rear shaft. I have pulled/wiggled on everything else I can think of with no luck of finding of anything loose.
One thing I did notice, is that the front axle is locked in all the time. How long it has been like this: years for all I know... I can flip the switch from 2wd to 4H and 4L. It all seems to work fine, I hear clicking, the 4x4 engages, the proper lights come on/off. The front axle will pull when supposed to. The transfer case seems to be working fine, but the front axle won't disengage. I am hoping this can be fixed cheaply/easily (DIYer), and also hoping this explains my low fuel mileage.
Front axle? Where to look or what to try and fix for the vibration?
