This past weekend I was coming down a mountain and lost brakes for a moment. Had to pump the pedal to get it to slow down. Before I could get stopped to check it out, it happened again and I had to pump the pedal again. I’ve been down bigger hills and never had this happen. It was a butt puckering moment.
After I got it stopped to see what was wrong, I expected to see a busted brake line (etc…), but found nothing other than where some fluid had expelled from the master cylinder cap. The brakes worked fine the rest of the day and again when I took it off the trailer when I got home. I can only assume that the brakes got so hot that it boiled the brake fluid and put some air bubbles in the line, because now my pedal does feel a "little" spongey…..but they still work.
It has been freezing and I have been busy the last couple of days, so I haven’t had the chance to take off the wheels and check the pads, but the rotors are not scored or gouged. The pads might be thin (and maybe that contributed to the heat buildup), but they shouldn’t be metal to metal yet.
Anybody have any thoughts, or have you ran into this before? I’ve been into SXS’s for 10 years now and this is a first for me.
