Geo Prizm Brake Master Cylinder
How to Identify the Causes of Geo Prizm Brake Master Cylinder Issues
The stopping power of your vehicle greatly depends on the Geo Prizm brake master cylinder. This device controls the amount of hydraulic fluid within the brake system. Under normal driving conditions, this component stays intact and undamaged. However, that's not always the case. Extreme mechanical vibrations and stress can cause the brake master cylinder to crack and experience several problems. These will give you so much trouble, so you better hurry and troubleshoot the problems.
Leak or seepage is the primary brake issue in most Geo Prizms. This usually happens when the brake master cylinder comes off from its proper mounting. This device is typically attached to the brake booster. But because of the car's constant movement, it may come loose. This causes the hydraulic fluid to seep out of the cylinder. To check for leaks, you need to open your hood and check your brake fluid container. If its level seems low even if you just recently added fluid in it, it's possible that there is leak in the system. Inspect the mounting area as well. If you see a little fluid around the cylinder and the brake booster, there's no need to worry because that's normal. A lot of seepage, on the other hand, means that the cylinder is detached from the brake booster.
Bypass is a kind of leak that usually occurs inside the brake master cylinder. This particular brake issue causes the brake pedal to sink. Once you encounter this, you have to carefully inspect the sealing cup of the brake master cylinder. A damaged seal is the major culprit behind this problem. Install new seals and re-bleed the cylinder to restore the normal operation of your brakes.
Brakes that apply automatically is a grave danger for you. This can happen when the vent port in the cylinder is clogged. A blocked port would not allow the brake fluid to flow through the hoses. When the fluid gets stuck, it can heat up and trigger the brakes to operate even when they're not needed. If you keep on experiencing this trouble, you need to buy a repair kit that can help you take out the blockage from your brake master cylinder. This kit is available at any local auto parts store.
