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) |

If you are getting fluid into the switch the m/c and it’s seals are shot.

QUOTE(Superhawk996 @ Sep 17 2025, 08:47 AM)  If you are getting fluid into the switch the m/c and it’s seals are shot. It's leaking from around the threads of switch as far as I can tell right now. Also if MC is failing would it make any noise like a whirling/whining noise? Last time I drove her at the end of about 20 mile twisty drive I could hear that kind of noise. could feel vibration when hand on top of gas tank.(fuel pump under tank). Still had full hard breaking also at end of drive (thank god) I think I have two problems. brake leak and possible fuel pump. Just shoot me now! Really feel like I am done.!!!!! |
