Have you definitely got it plumbed in right?

Normally on hydraulic handbrakes you plumb the master cylinder for the handbrake in backwards. You connect your rear circuit master cylinder 'out' from the pedal box to the handbrake master cylinder 'out'. The handbrake master cylinder 'in' then goes to the rear brakes.

This allows the fluid to flow through the handbrake for normal brake operation, but will still pressurise the rear brakes when the handbrake is operated.

I've never had to do anything but bleed as normal on the rear brakes.

We dont plumb them in like that Will, maybe I've read it wrong? We go from brake master cylinder to the 'in' (or what you'd normally plumb the reservoir to) and the outlet goes to the rear brakes.

But to answer the guys question, to bleed the handbrake you simply bleed the rear brakes, you could loosen the outlet pipe on the hyd h/brake and pump it that way and then blled the rear brakes if you're getting into difficulty.

I've tried it both ways with the hoses and cannot get the air out of the system, a little strange I think, I'll keep trying though

mine was as per how martin said.



the fluid in goes to the rear of the cylinder, and the out goes to the rear brakes.
