leaking master brake cylinder

Post by zuurb »

Because my master brakecylinder in my Daimler V8 was leaking i renewed all seals.
the master cylinder is of the Dunlop type.
I refilled the brakeoil reservoir and bleeded both front brake calipers.
I experience that the car is braking as normal, but the brake pedal is, after using, not coming back spontaneously as before.
It feels as if the pedal is slightly hanging in the returnmovement.
Can anybody tell me what is the reasen and how to cure it

Firstly I would suggest you bleed the whole system not just the front part.

I'm not familiar with that particular master cylinder but most cylinders have a small hole somewhere along the bore to allow the cylinder to refill with fluid from the reservoir. Sometimes that can get blocked and cause problems like you describe.

Worth having a look to see if it is clear or not.
