Probably goes along with the above, on my 7 I recently lost my left brake, turns out to have been a o-ring in the brake caliper (Maybe, it was def shot and we replaced it. Should have replaced both sides when I had the chance. Anyone know what size to order?) Anyhow we replace the oil ring on the left, and bled the brakes on the left, but still didn't have good braking on the left. I jumped into the Co-pilot seat (right) and tried the brakes, Left worked great, Right didn't (complete opposite from pilot seat). We then bled both sides and the pilot seat works, but the copilot seat still is not working as good as I think it should. The Mech thought it could be the master Cylinder on the Co-pilot side, I think there may still be an air bubble in the lines.
Any guesses?
