i have twice had the feeling of brakes dragging. I removed the sliding pins in the calipers (they were all ok)and re greased them. I couldnt see any faults.


It has happened again, you need revs to keep moving, and with the car stopped, it will not roll in N. Leave it for an hr, and it is ok. Between the happenings, there has been a lot of driving.

Tomorrow i will have a good look physically at the calipers and also the hand brake(not sure how it works, but will find out). I then intend to remove the master cylinder and check that the piston is moving ok (non TRC) then put in new fluid and bleed the brakes.


any one had this happen or have any thoughts?
can the gear box give these symptoms?

Check rear hand brake drums Tom, would be hot after 2 ks if they are rubbing.

rear brakes were also not working fully. Removed the master cylinder and the rear section of the piston assy was "seized' in. Installed 2nd hand master cylinder, bled brakes , all good.
After a run , front rotors 120c and rears 108c

The master cylinder did not seal tight, so maybe moisture got in and contaminated the seals?
