Brake problem, Urgent!

[hahshem]

Hi, my m8 has a seat leon an every time he turns full lock right the brake pedal goes right to the floor, but only on right turn. Its fine otherwise.
Any help would be greatly appreciated.

any signs of a leak from anywhere on the system?

Hmm thats well weird.

[hahshem]

Nah no signs of any leaks. Its really puzzling me. Would this kinda fault show on diagnostics test?
Still i have no idea what would cause it as its only when toy turn right.:confused:.

Does the peddle come back up then?
Is the pedal dipping also causing the brakes to come on?
Sounds like a problem with the hydraulics system, it'll be fun finding that one I assure you but I'll bet a quid on the servo or pedal mech being beyond repair

Does sound like the servo is opening up to return, maybe a back pressure from the RH brake line as it flexes which is pushing back to dislodge a seal, opening the system to the reservoir.

Yes the pedal does come back up, n it doesnt stay on slightly.
Am going to have a look into it more on the weekend for him.
