It semms to be much worse if i'm heavy with the brakes and the engine is on, It's as if the car is braking all on it's own. Or at least when i brake they dont return, But i know everything is free ????
Just a thought,but what happens if you disconnect the vaccum pipe to the servo and then pump the brakes?.Do they still stick on?.

I'd rather push my Alfa than drive a BMW....

Re: Front brakes sticking on!!!

I've had the same problem with sticking brakes on my Laguna II. But it occurs only on rainy weather... driving for a longer time on a higway makes the breaks stick or even worse they do not react for a while. When I pump them or break aggressively than all is good...for a while. On normal weather breaks are OK, just squealing.

Re: Front brakes sticking on!!!

When your foot is off the pedal is the rod that
pushes the master cylinder piston allowing it to
return all the way, if not the piston will not uncover
the port to the brake fluid res and pressure will
build up.

Who would design a vehicle that falls over when you stop?

If you find a fix for your problem please let us know it will help others.

Talking Re: Front brakes sticking on!!!

Well i thought it was a master cylinder, until i jacked up the rear and they were free! I just tried to free off the bleed nipples and guess what, The Ba****** have both just snapped! used loads of wd40 too..... I personally think it's something to do with the abs / traction control or something in the electrical system, Renault have been so unhelpful as they do not even want to discuss any problems with the car unless i take it in for a diagnostics. I'll drill and retap the calipers abd try and re-bleed the system and try again. If that doesn't cure it i'm going to take a big hammer to it.
