I’ve had problems with the left brake not working. It’s only the left brake and it usually works from the copilot’s side but the pilot’s side goes to the floor with no braking. We’ve rebuilt the master cylinder and that worked for a while but now the problem is back. Anybody else run into this issue?
If you have rebuilt the master, then the only other component is the caliper. Maybe a rebuild of it with a new MS28775-224 o-ring and a brake bleed and you should be back in business.
