Hi,

you may have read that my front brake seized on and through me off my bike.

I have completely dismantled the front brake and believe the problem is in the master cylinder. There are two holes at the bottom of the reservoir. The smaller one of the two, when the components are installed is cover by the rubber cup that fits on the spring, and uncovered when the lever is pulled in.

Is this correct, how does the brake fluid return after the brake has been released, through the smaller or larger hole?

When I bled the brake it was very hard to get the fluid to pass to the caliper. I had to use pneumatic pressure to bleed the brake, via one of those easy bleeds that attaches the valve on the inner tube.

Thanks in advance,

Andy
