Brake Replacement Master Cylinder Troubleshooting For Brakes!
Do you feel confident that when your auto mechanic recommends a brake replacement, it is really true? How can he tell if the master cylinder on your brakes has failed? Or is he just trying to push an add-on to the other repairs on your car. How do you know if he is doing his job correctly and looking after your best interests and your safety, rather than taking you for a ride with a brake replacement?
Signs the Master Cylinder is failing:
* Soft, squishy feeling when you press down on the pedal – As constant pressure is maintained on the pedal (like at a stop light), it will begin to sink to the floor as the brake fluid leaks internally to the master cylinder. This is called “extended travel.” You may have to “pump” the pedal to regain normal pressure and keep the car from moving forward as the brakes slowly release. The red warning dash light should come on to indicate low fluid, or excessive movement “travel.” The fluid level alone isnt an indication of a good or bad master cylinder. Typically, the leak is internal, leaking past internal O-rings, so there is no obvious external sign that the master cylinder is “bad.”
