Today I took some time off to set the front brake up.
Initially I couldn’t get it to tighten up evenly.
First thing I tried was a pair of new Hel washers on the master. The old ones let brake fluid through. This tightened everything up.
Eventually I felt that the hose from the brake fluid calliper was “sweating” out fluid. Changed it to a real hydraulic hose meant for a car. Overkill maybe but it did the job.
The hydraulic fluid calliper was bought of chasspeed. God piece if kit. I could just have had the fluid in the hose but this felt safer.
While filling up. I saw that fluid was letting out however I tried to tighten things up. I removed the slave and tried it up in the open to see if it leaked from within or from the banjo connections.
The fault was the washers. I found it out after I changed the banjo itself to a Hel one and it still leaked. I replaced the washers to a Hel one and managed to seal it up. Suddenly the system got tightened up quickly and my semi hydraulic now works.
Fitted the big circlip and fixed the front brake lever up with a strap to hold it tight and let air wander up during the night.
As mentioned the hydraulic fluid container is from Chasspeed. All the hydraulic Hel parts as cables, banjos and good washers are from Beedspeed and the slave “puck” cylinder is from Scootrs. The semi master is of a piaggio bike.
