Brake calipers use hydraulic vigour to the brake pads. The pads squeeze against the rotor on Everyone side and slow the vehicle. This is alike course caliper brakes profession on a bicycle. When you activate the cable-driven share brake, the caliper squeezes the pads on either side of the tire rim and slows the bicycle. The contrariness between the two is hydraulic force. There are a uncommon reasons why a brake caliper can cease functioning the habit it was intended to. Checking the caliper for performance issues is recommended when your brakes aren't working properly.
Instructions
1. Lift and back the vehicle using a jack and jack stand(s). Be firm to loosen the lug nuts with a lug wrench before lifting and supporting the vehicle.
2.3. Situate the C-clamp over the caliper so the backside manage of the C-clamp sits against the outboard pad and the top of the clamp sits over the caliper housing. Tighten the clamp in direction to compress the caliper piston. Provided the piston does not retract or gives Exorbitant resistence, the piston is compromised and requires replacement.
Peep the brake hose and caliper for visible signs of brake fluid leaks. Brake hoses with visible cracks or Degeneration should be replaced at the moment. Brake fluid seeping or leaking from the caliper piston may or may not be visible until the caliper is removed. An Exorbitant leak Testament be distinguishable and the caliper should be replaced. When checking rear calipers, be aware that some depend upon screwing in the piston which requires a definite baggage tools in line to accomplish. Trying to compress a screw-in piston with a C-clamp or passion Slogan can damage the piston or clamp or both. Screw-in piston type calipers are lone used on some rear CD brake systems.
4. Ploy the caliper with your hands once the piston is retracted. Free-floating calipers use slides that compulsion to stir back and forth. The slides may be seperate or integrated with the caliper bolts. It is not rare for the slide or slide bolts to corrode and prevent the caliper from Stirring properly. To place the headache the caliper would require to be removed by removing the caliper director bolts or slide bolts. The bolts would have need cleaning and re-lubricating or replaced and lubricated. Internal slides can further be maintained in this fashion.
5. Remove the pads and compare the pad wear from both. One pad enervating extended than the other may display a sticking piston or sticking slide. Habitual side object in this contingency admit the vehicle pulling to one side when the brake pedal is applied. Whether the slide or piston is beyond reconditioning, replace the caliper and then bleed the brake system
6. Bleed the brake system any time the hydraulic system is exposed to air. Brake crimps placed on the brake hoses will prevent too much air from entering the system, but bleeding will still be required. To bleed the brake incorporate the assistance of someone to pump the foot brake pedal four to five times and hold it in the down position. Open the bleeder screw on the caliper and allow air to purge from the brake lines. Strategically place a drip pan below the caliper to catch the brake fluid. Close the bleeder screw while the pedal is still in the down position and then repeat until the pedal feels firm. Add more brake fluid to the master cylinder to prevent it from running dry when bleeding brakes. Also, return the cap or cover to the master cylinder before allowing the assistant to pump the brake pedal again.
