In addition to the prescribed intervals, the brakes must be inspected when the wheels come off and any time there is suspicion of a defect. One or more of these symptoms could indicate possible brake system defects: pulling of the vehicle to one side while pressing on the brake pedal; noise coming from the brakes that sounds like a squeak or scraping sound; excessive travel in the brake pedal while braking-this is known as pedal pulsation; when applying pressure on brake pad, it feels like you are pumping up air instead of braking; this can be caused by leaks in brake fluid usually found inside tire or wheel. The first step in inspecting brakes involves loosening wheel lug nuts and raising the vehicle securely with jackstands. Remove wheels. There are two pads per caliper for front and rear disc brakes. Check pad thickness by looking at each end of caliper, and through inspection window in caliper body. If lining material measures less than required, replace pads. In case determination of precise thickness is hard remove caliper(s) plus pads should be taken out for further examination. Clean them using brake cleaner and re-measure their thickness. Calculate disc thickness still has service life remaining by utilizing micrometer. Inspect all brake lines and hoses before installing wheels for damage, wear, deformation, cracks, corrosion leakage bends twists being careful not to twist them excessively during installation process.To examine rear drum brakes ensure that parking break is released then remove drake drums.Clean braked up assembly noting its lining material thickens at both front and rear shoes.Makesureallbrakeassemblies are connectedby springandarein goodcondition.Lightlywipe insidesofdrums checkingforcracks,scoremarks deepscratchesandhardspots.If suchabnormalitiesarefound repeatprocedureonremainingwheel.Optimally perform these tests from driver's seat to check whether booster works correctly.Ifyou applythebrakesbutthey workdifferently,thenthebrake booster hasfailed. Slowly pull up the parking brake and count how many clicks it takes to get all the way up. If you hear exactly that number of clicks, then the adjustment is right. Another way to check operation of a parking brake is on a steep hill with vehicle parked and with transaxle in Neutral.Parking brake is not adjusted enough if car rolls when parking brake is applied.
