Checking Brake System, Brake Hoses and Removing Master Cylinder
- System Evaluation
When Lambert test drove our car, it stopped nice and straight but the pedal was mushy. He discovered that there was a torn master cylinder boot. The brakes, on the other hand, looked really good. They were solid, but if you have a brake line that looks like this it is critically important that you replace it because this is a single action unit. If you lose one brake line, your entire system goes down.
The brake hoses looked fresh. We did have a bad break hose, though. If you can see small cracks, the hose has been shot for a while. A new hose is a stark contrast to an old one.
- Removing Master Cylinder
- The master cylinder is located in the engine bay, behind the brake pedal. It stores the brake fluid.
- Remove tire and brake drum . Peel back and check the wheel cylinder. Ours was nice and dry, which is a good sign. If you have a lot of fluid there, you have a problem and need to replace.
- Begin by removing the electrical leads and then take the hydraulics off. You will have to catch the hydraulic fluid when you break the 3/4 nut free.
- Loosen the master cylinder and begin pulling the rest of the hydraulics off. Be careful not to lose the washers.
- Once the master cylinder is free, push the hydraulic lines down gently and pull the cylinder out. Your pedal will fall because all the tension is lost.
