OK, I changed the main cylinder (new part) because it went straight to the floor without brake power. Workshop said it was wrong fluid on the system. I changed all brake fluid and replaced with Dot +4.
After changing the cylinder the brakes locked. They do brake normally but does not let completly go, and my disks get hot. It is not impossible to drive, but the car struggles in 5th gear, and wont roll freely in gently downhill. However, the problem is solved by pulling the pedal gently outwards and by doing so after each braking it is possible to drive. This happends on all 4 wheels.
My trobleshooting in order: -Adjusted the pin rod in the brake booster inwards, to release pressure (if there) on to brake cylinder. -Adjusted the pedal inwards and outwards -Changed the brake booster (used part) -Replaced the vacuum hose to the booster -Changed all brake hoses -Disconnected ABS-fuses -Removed the brake light switch
And the problem is still there, and the brand workshop can't help me.
