matthews512 Posted January 13, 2015 Posted January 13, 2015 I've recently had my master cylinder and brake servo changed along with my front calipers and brake lines also the flexie hoses because my front brakes would seize on whilst driving after getting to hot and expanding after changing all of this they are still doing it could someone help me with this as I am now completely out of ideas an no one has been able to help me with this!! A y help would be appreahiated!! Quote
Starlet__SR Posted January 13, 2015 Posted January 13, 2015 Sounds like you may still have air in your system. The air is getting hot and expanding causing the brakes to start binding. If its not then then it could be your piston that isnt backing off when you release the pedal. Also worth checking your sliders are free aswell.Day Quote
Ryan_EP82 GT Posted January 14, 2015 Posted January 14, 2015 As said above sliders are probably stuck or a damaged rubber ring in the piston housing not pulling piston back Quote
matthews512 Posted January 14, 2015 Author Posted January 14, 2015 I've bleed the system countless time I've gone through 3litres of brake fluid and just put another new master cylinder on and problem is still there Quote
bucketep91 Posted January 14, 2015 Posted January 14, 2015 More than likely a sticky rear piston. Happens all the time with our cars in cold weather. I leave it in gear with the handbrake off when it's freezin Quote
matthews512 Posted January 16, 2015 Author Posted January 16, 2015 Its not the backs its only the front that do it so bad that I've now got two cracked discs and gone through a set of pad in about 500 miles its as if the pads are constantly touching and once they get to hot there expanding and gradually stopping the car but I don't seewhy they are doing that and how to sort it Its not the backs its only the front that do it so bad that I've now got two cracked discs and gone through a set of pad in about 500 miles its as if the pads are constantly touching and once they get to hot there expanding and gradually stopping the car but I don't seewhy they are doing that and how to sort it Quote
toyotag2014 Posted January 17, 2015 Posted January 17, 2015 this deffinatly sounds like piston siezure to me bud you should be able to to pull rubber forward spray some white grease in their or rostoff and then push the piston back in calliper and then get a mate to push the brakes with you down at the piston with clamp over it so it doesnt pop out then push it back in and work it back and forth ect its probs got no grease in their so just lube it up then put back on see if this works if not new calliper im thinking dude Quote
matthews512 Posted January 17, 2015 Author Posted January 17, 2015 I replaced both of the front calipers to start with it didn't do a thing :/ could it have something to do with my syncro ? As it happens to both of the front calipers at the same time ? Quote
aidanep71 Posted January 17, 2015 Posted January 17, 2015 U sure your pedal isn't adjusted too much Quote
matthews512 Posted January 18, 2015 Author Posted January 18, 2015 How do you go about adjusting the pedal I ? Quote
aidanep71 Posted January 18, 2015 Posted January 18, 2015 Same as doing the clutch there's a rod going onto the pedal that can be adjusted... Have you free play on the pedal when cold Quote
matthews512 Posted January 18, 2015 Author Posted January 18, 2015 There's a little play not much though Quote
FMuscle Posted January 19, 2015 Posted January 19, 2015 Might be just the pedal's free play, no play in the master. Quote
