Okay, so.... I don't know what's going on... I adjusted my RPM switch settings and now my brakes don't work. I checked all of my hoses, especially the brake booster hose. Everything is connected, nothing is loose. When I step on the brakes (with car on) I hear a hissing sound. When the car is off, no hissing but the brake pedal does regain pressure. Any ideas?

 

Check for leakes. Does the pedal go to the floor ? Possibly Brake booster

Hissing like air or fluid? Air, and your booster is shot, fluid and you've got a leak. How's the fluid level in the BMC?

What did you touch when adjusting your RPM switch? Is it in the cabin or (for some reason) in the engine bay? Definitely go over the area you were in a few times, check everything that you could've/might've touched.

Otherwise, it could just be a coincidence.

 

Pedal goes straight to the floor. Even the manual rod doesn't seem to be working. Hissing like air. I didn't see any fluid and the resevoir is still full. Yes the RPM switch is in the cabin. Most likely a coincidence but even still. How can I check to see if the booster is shot?

 

BUMP!!!!

 

Low and behold! My brakes were cut! (I guess I shouldn't have mad those people mad, j/k) Police are getting involved though. This is ridiculous..... My days just keep getting better and better.
