In my car the brakes work fine for like 2 miles, after that the pedal is stiff and wont move at all, and you can feel the brakes are on and smell them burning, and almost caused me to wreck, changed brake booster and still same problem, any help would be greatly apreciated

 

Piston in the caliper getting stuck??

 

Damaged calipers(pistons), lines, sliding pins?
Have you checked any of those?

 

no but it does seam to be coming from the right side where the brakes, heat up hopefuly the next day or two i can check into it more

 

pistons and lines seam ok, put antoehr brake booster in and still same problems, bleed all lines, even used diagnostic scanner and did automated bleed, AND STILL CANT GET THEM RIGHT

 

anyone?

 

Did you check the caliper pins yet?

 

yep caliper pins were cleaned and greased

 

even was told to pull the abs fuses, so the abs pump would not come on and it still does it

 

Is abs turning on? If it is when? Maybe try a new master cylinder?

 

bad master cyclinder? mine is bad and i've only got 60K miles on the car and the rear brake pads seem to be untouched after 5k miles and for me... i normally have to change pads every 10k if not sooner.

 

well i tried a master cylinder and still same problem, i am goin to try front brake hoses since this seams to be about the only thing i have not changed

 

now put stainless brake lines still no help

 

Did this just all of a sudden start happening or had you done any brake work prior to this? Have you checked to see if you have a rotor that may be warped. Should not be this hard to figure this out. Just hate you having to spend so much cash with no positive result. You say it seems to be from the right side . Is it possible the right side is doing all the work and the problem is actually coming from the left. Just a thought. Would like to have the car in front of me to try and help you out. Good luck

 

well its both front wheels locking up, i been thinking the abs unit but everyoen said thats wrong but this is the last thing to change and im do it this weekend, it sucks

 

officially ready to kill myself, put abs unit in bleed brakes again and it still locke dup roters turned red hot

 

only thing left is calipers but wats the chances of both them goin bad at same time?

 

bump someone got to knwo the answer to this

 

maybe proportioning valve. or check if there is a kink in any of the brake lines. and not just to the caliper.

__________________________ SUMMARY__________________________

Hi All, i got 8 replies + most said 'contaminated brake system
+master cylinder cup seals swelled/as well as possibly
calipers w/cyl's etc, i did replace the frt. hoses previous to
request + flushed system/adjusted stoplite swx. Customer said
the next day that It was acting O.K., therefore he has not
returned,If he does i will reinitiate Help request,or
close/w-fix. My opinion after the work was: it still has a
problem binding down/heating brks,but he seems satisfied for
the time being, thanx, g.b.

Hopfully this will help
