What kind of brake line is it and if is replicable with regular brake line? I'm just replacing long line between front and back splitter block and just would like to know what is it. What is purpose of that braiding (?) at front brake lines and why they wind down instead of going straight. Part of that long line is braided too, part that go across frame.
View 3 RepliesWhy the brake lines have 2 or 3 coils in them near the master cylinder? Makes it a real pain to work on anything down in that area. Always snags ratchets and stuff...
My brother and I were discussing it the other nite, and the conclusion we came up with was, the first guy ever who was installing a brake system had tubing that was a couple feet too long, and couldn't find a tubing cutter, so he coiled them up.
Then the next guy saw that and figured "hmm, so THAT'S how it's done", and so on... Kinda like the story about the lady who always cut off both ends of her ham before she put it in the broiler..
I have a 79 f150. I changed two brake lines and master cylinder and bleed,and more bleed,but still very soft all most to floor? wheel cylinders look good.
View 2 RepliesWhich line goes to front brakes and which to rear from the master cylinder?
View 1 Replies...Is there anything special that needs to be done for brake bleeding after putting in a new master cylinder? I decided today to flush my system with my vacuum bleeder and now my pedal slowly falls to the floor at a light...No problems in a panic stop or otherwise, just falls to the floor slowly when braking...no leaks, so I'm assuming a master cylinder is an order....
View 14 Repliesll, I changed out the master cylinder on my 2002 F-150, disk brakes front and back w/ ABS. Bleed all the air out and bench bleed the master cylinder. I have good pedal but the brake light will not go out.
View 6 RepliesI have replaced booster, master cylinder, all four callipers, and bled the brake system a number of times on my 2000 F-150 4x4. and still the pedal is wicked spongy, is there some other problem?
View 6 RepliesThe cruise switch on my brake master cylinder is bad and causing the cruise to not work. I have it bypassed with a jumper wire and it works fine. is there any reason not to do this?
View 11 RepliesStopped after a hard pull and noticed I had coolant dripping off the front sensor on the Brake Master cylinder. Coolant level was down in the Degas bottle. Searched everywhere for the source of the leak, and couldn't see anything. Today the drip had stopped, but when I squeezed the rear heater return hose under the Degas bottle it appeared to have a wet spot form.
I'm thinking I have a very tiny pin hole, and plan on pressurizing the system to see if I can determine for sure this is where it is. Before I do though, where this high pressure leak might be coming from? Degas bottle and cap is less than a year old. Doesn't appear to be any signs of leaks around the clamps. That rear heater hose.
I tried to replace my brake master cylinder today but wasn't able to because of a plug
It's the black plug on the drivers side, the connector is upside down so I can't see how to unplug it I tried for an hour then got too frustrated I had to come inside
My Haynes manual says "unplug" obviously
Blew a hole in the 3/16 inch line to the rear on the left frame rail, behind the gas tank. Lost all brake function.
Got the truck home and inspected. The line was rusted bad about 6 ft long from the connection at the rear hose to the axle, up to the rear seat area ( crew cab). From the drivers seat forward, the line looks very good. The line across the rear axle from left to right looks very good. I bought two 50 inch standard lines 3/16 inch. Started at the rear hose connection 6 inches behind the gas tank and ran forward to the rear seat area.
Cut about 32 inches of the other 51 inch line and connected and ran forward to below the front seat area. There is a metric connector at this point. I cut an inch in front of it to eliminate it. NAPA sells a high psi compression fitting ( steel , 10,000#) that you can connect two 3/16 inch lines together. I did that under the drivers foot area. I have done two different 2002 F150s in the last year due to this failure. Something to look into. Not nice to loose brakes in traffic.
If your worried about the steel compression fitting, don't. I have used these on several cars and trucks over the last 15 years. Make sure you get the STEEL high pressure compression fitting. Total line replaced on CREW cab, 51 + 32 inches. Pops right back into the original plastic clamps.... I might mention, that is where the failure was, under the plastic clamp at the rear end of the gas tank area.......... crud must collect on the clamp.
I have a 1999 Ford F-150 4X4 w/4.6L V8 W code, I recently lost all brakes. The primary line from Master Cylinder to ABS Pump rusted out completely. Replaced them but the other lines from ABS Pump to wheels are looking real bad. So I need to replace them, however I have no idea what the routing system looks like. Looking for a 97-03 F-150 Brake Line Diagram? I live at the jersey shore... so yeah rust is extremely common.... unfortunately.Also, where to get line assemblies?
View 7 RepliesJust purchased a 2003 GX470 with 160k and after the low brake fluid light came on I noticed the master cylinder had a leak. After removing the cover it appears the fluid has leaked for quite some time as the paint has started pealing from the frame. The brakes however appear to be working correctly. Upon purchase the front calipers were seized and I replaced both front calipers.
After having someone depress the brake pedal while I watched, the fluid leaks from the end of the master cylinder each time pedal is pressed in.
After doing some research it appears there is a rebuild kit for the master cylinder.
I recently noticed that my brake fluid was leaking in my 2003 Hyundai Elantra and upon further inspection I found the leak was coming from a part near the master cylinder. I looked online and couldn't figure out if this part was part of the master cylinder or brake line or a part all on its own. I tried tightening it but It still leaks some. I read a similar post online and that it could just be that the washer needs replaced but I just wanted to check on here to see what the part is called and if I should just replace the whole thing. I included photos as well.
View 7 RepliesI replaced my MC cap and gasket less than a year ago with a Dorman replacement and I'm leaking again, already. I don't want this to be an annual thing! Any good quality replacement? Is there any tip or trick to get the gasket to seal better?
View 9 RepliesEarly 70's Ford truck. The brake MC fluid is filled but not overfilled, and doesn't leak at all when the truck is parked. It can sit there for a month and never leak a drop, parked. But when I drive the truck, even just around the block, then park, and look inside the engine compartment immediately the brake MC is dripping brake fluid. It appears the leaking mode is by the fluid somehow jumping up and coming over the top edge of the MC when the truck is in motion or when the brakes are applied. All my diy'er years of replacing brake master cylinders on Ford Galaxies, VW Rabbits, Corollas, and this truck, I've never seen this kind of weird brake problem before. On this MC design it seems there's sort of a rubber baffle inside the lid of the MC, and that's present and accounted for.
View 17 RepliesMy son's 2006 F-150 4x4, with 107,000 miles, has in intermittent brake light on. I replaced the rear pads, as they were nearly into the rotors. The brake pedal feels fine in all braking conditions. Could the master cylinder still be going bad? Anything else to check?
View 4 Replies1987 F-350 460 Auto Trans. Brake Pedal slowly going to the floor. Stopped at a red light yesterday on a slight down hill and I noticed the brake pedal slowly going to the floor. I had to put the truck in Park to avoid bumping into the car in front of me. I checked brake fluid level and still at the full level, check rims for brake fluid leak from brake cylinder, none. Could my master cyclinder need rebuilding or is my vacume diaphragm going. Not sure thats what its called.

View 6 RepliesI replaced the master cylinder 2 months ago and now every now and then the rear lock up for a second. its only happened a couple of times. Pulled the wheels and everything is in place with nominal wear with clean drums and rotors. Am at a loss as to why this is happening.
View 1 RepliesA few years ago I (for him) replaced all 4 calipers, rotors, pads, etc....things were good. Just recently he replaced his Brake Booster and Master Cylinder (not sure what led to this), but long story short everything is back together and he doesn't have brakes.
My GUESS is that the system needs a good flush, new fluid, etc....
My problem is I'm unsure how to bleed the ABS system. A few google searched indicate I need a scan tool, but is there another way? Can I jump something.
So my question, how do I completely bleed the brake system on this truck?
