Discovered a fluid leak at the brake switch in the Master Cylinder (19mm).
Two questions, What kind of washer is between switch and MC? Metal/fiber? If I take the switch out will I loose the brake fluid? Thanks Renee (IMG:style_emoticons/default/driving-girl.gif) (IMG:style_emoticons/default/headbang.gif) |

Definitely curious that it has failed by leaking at the differential pressure pistons. Much more common to fail at the primary pistons and then it leaks into the pedal box area
I guess the bright side is you don’t have a mess in the floor pan to clean up. judging by the paint it doesn’t look that old. |
