How to Tell if a Brake Caliper is Bad
A brake caliper is one of many authoritative parts of a brake system. Combined with brake pads, they have the enormous task of changing the vehicle ’ s forward motion to heat which stops the vehicle. If they don ’ triiodothyronine work by rights, stopping the vehicle can be very difficult. How do you identify a bad brake caliper ? The steps below will help you identify whether or not your brake caliper is bad .
step 1 : visually Inspect the Exterior and Operation of the Caliper
Visually inspect the outside of the brake caliper. Look for cracks and brake fluid escape. If you see cracks, the unit needs to be replaced. Areas which are leaking will be wet or have streaks. Have an assistant engage the brakes while you observe its operation. If the caliper does not move or you can hush turn the rotor with the brakes applied, check whether or not brake fluid is reaching the caliper.

Be certain the end of the hosiery is submerged below the bracken fluid. This keeps air from getting into the system. Open the valve and have an adjunct apply the brakes. If fluent flows into the container, then fluid is reaching the caliper. If you see bubbles, then there is air in the system that must be removed. If no fluid flows into the jar, check your brake lines and the master cylinder for problems. If extra fluent flows into the glass clash from the container, then the problem is the caliper .
gradation 3 : check If the Caliper Floats Properly
If the caliper moves when the brakes are applied, pay attention to how smooth the gesture is. One problem could be that the float pins need lubrication. If the caliper doesn ’ deoxythymidine monophosphate move, then watch to see if the brake pad itself shows any signboard of try movement. If the pad tries to move, then the piston behind the pad is working and the caliper is not floating properly. The pins could be damaged or they need to be removed, cleaned and relubricated.
step 4 : see If the Piston Is Working properly
When the brakes are applied, the piston should push on one of the brake pads, causing the caliper to float. Since a second base bracken diggings is connected to the floating separate of the caliper, the two brake pads squeeze the rotor, causing it to stop rotate. If the brake embroider in movement of the piston doesn ’ thymine try to move when the brakes are applied, there ’ s a trouble with the piston.
