Trident 95 Front Brake Master Cylinder

Tony Hayden · Jul 12, 2020

Hi Guys, What has happened? New Goodridge brake & clutch hoses fitted, master cylinders overhauled, clutch and rear brake bled but cant bleed front brakes as i cant get any fluid down to the calipers. I think the problem is with the master cylinder, yet i can see the piston moving. Any ideas! Have i reassembled the master cylinder piston wrong?

Try a vacuum bleeder on it.

Never tried rebuilding any brake cylinder, but I would suggest having another look at what you have done just in case something is out of place. I've made that sort of mistake in the past!

Have you tried opening both caliper bleed nipples together and then slowly pulling the lever?
If you don’t get anything out then I’d be relooking at your assembly of the master cylinder.

Assuming the brake cylinder is assembled correctly (the lips on the seals need to be the right way round)
Pump the lever really quickly to start things flowing

Update: Stripped the master cylinder, all ok. Turns out the master cylinder was badly airlocked, after a lot of phaffing to clear it i now have fully functioning front brakes.
