Brakes staying on.

[BigG]

When ive been out for a bit in the bus in stop start traffic the brakes start to bind and stay on like the hand brakes been applied :shock:

If I leave it for ten minutes or so with the engine off it frees of, I cant find anything wrong at the wheels, could it be a servo prob?

The rubber brakelines at the wheels can colapse inside and act like "one way valves". You might have to change them.

Insufficient clearance at the push rod that operates the master cylinder from the pedal should be 1mm, usually only happens if you had the master cylinder off or a new one fitted.

Could also be blocked compensation port in the master cylinder, will mean taking it apart to clean.

Cheers fellas, the master cylinder was removed a couple of months ago when I fitted adjusters to the beam so I will check the rod.
The brake pipes at the back were replaced by the last owner about 4 years ago but un sure of how good they are so will check those too.
