Thanks for the tips.
The front brake seems to work fine when left alone to cool down. After riding it for a few minutes and getting it warmed up it will seize on me again, any ideas??
Hi Kenny. Welcome to the VR from snowy Alberta Canada. Yes, Iím looking out the front window and watching the snow fall.
As to your hydraulic brake problem, the fact that the lockup occurs after the brakes warm up indicates a strong likelihood that expanding brake fluid is doing the lock up for you.
The fluid will naturally expand when ir warms but there is a feature in the master cylinder that is supposed to allow the expanded fluid back to the cylinder so there is something that is preventing that from happening.
1. In the bottom of the master cylinder reservoir are two holes. One large and one small.
The large hole is behind the piston to refill the pumping chamber in front of the piston cup when you pump the lever. (You can ask how that happens later). The small hole is in front of the piston - on the caliper side- to allow the fluid to return to the reservoir when you release the brake lever and also as the fluid expands.
2. The second possible cause occurs inside the brake hose when the hose deteriorates due to age of the system. The lining of the hose acts as a one way valve to hold the fluid in the caliper.
I would check the master cylinder reservoir first.
Two things are the major causes of the problem in this location.
1. Debris in the bottom of the reservoir that gets stuck in the little hole - and by little, Iím talking 0.010Ē -
2. The mispositioning of the piston in its resting position. When the brake is released the piston Normally sits between the two holes. If the piston is forced to sit slightly in front of the hole, fluid canít return.
a. Corrosion in the cylinder or dirt behind the piston.
b. The push rod between the lever and the piston is not in its proper place due to a reassembly problem at some time in the past.
Hope this gives you some results because this is all that comes to mind.
