Front Brakes Locking Up

[silver ghost]

my front calipers are clamping up on rotors and are not releasing car has only done 60,000 klm have tryed new m/cyl but I think it is the calipers if you bleed the brake fluid you can move the wheels only have std calipers with dba 4000 rotors, that I have burnt to a crisp now, has any one had this problem before?

Brake booster will be dicked. Atmo valve will be leaking and allowing the the booster too gradually pressurize the brakes system

the back brakes are not locking up only the front two when the mecanic had it on the hoist need some brembos lol

The fronts get more pressure than the rear so they will lock before the rears.

Take the master cyl off, start the car and i bet the actuator rod in the brake booster moves out

should I change the booster over to the fpv one as its bigger for the brembos?

[Ralph Wiggum]

booster is the same, master cylinder is bigger on FPV equipped brembo's
