Symptom:

If you've been driving along for a while and you come to a stop light and hit the brake and the pedal drops to the floor without you slowing down at all... Downright terrifying when you are getting closer and closer to the car ahead and you're not stopping! You hit the brake again, and pressure starts to build up pressure and your brakes work and you slow down. PHEW! If this has happened, I would immediately check your brake fluid level and brakes lines and such. If everything is okay, then it might be your Master Brake Cylinder. They go bad after a while. Luckily, this is an easy and cheap fix.

Project Summary - Replacing Master Brake Cylinder
Difficulty Scale 5
Parts Cost $30
Labor Time 1 hour
Stopping in time... Priceless

This is the Master Brake Cylinder, and where it is located.

Don't read unless you're board: I was reading a chilton manual the other day, trying to figure out how to replace an O2 sensor for a subaru for a member in the family, and these manuals are so poorly written. I was trying to simply FIND the o2 sensor, where those japanese buried it into this engine, so I figured this manual would help. There was no pictures of where it is or anything, but the first step was "Remove the old O2 Sensor". Idiots! So yeah, excuse the rant. Tell me where something is, before you tell me what to do with it...

1. Put pan under Master Brake

2. Remove

3. Replace & hook back up. Fill with fluid, bleed brakes. BTW, you can do it manually, or you can use:

Mityvac Vacuum Test Kit - $64.95

You can get it here @ Performance Products,

 

Which has a brake bleeder tool on it.
