One of the most forgotten Brake components is caliper. Since every person driving the vehicle is not an expert and ignore the brake caliper service. Did you know that as per the recommendations of expert, it is necessary to service brake caliper after every two years or 40,000 Kms? Brake Caliper servicing is not a typical brake service but is somewhat different from it.
What are Brake calipers, and why they are important?
Brake calipers house the brake pads and, using brackets, pistons, and calipers side pins when help push the pads into the brake rotors when you apply the brake.
With the passage of time, the side pins that referred above use their lubrication and don’t slide the calipers well. With lack of lubrication, the following things start to happen;
- That Brake’s don’t contact the rotor correctly; brake pads wear unevenly.
- The side pin can get stuck. This causes the brake pad to continually contact the rotor and leading to heat buildup, resulting in faster wear and tear of brake pads
- Brake stopping power of your vehicle may become weak due to the brake pads not hitting the full surface of the brake rotor.
All this results that we are not fully getting used to the brake pads and it is just like burning or throwing dollars away.
How Brake Caliper service is undertaken
Before servicing the Brake caliper, the pressure in the anti-lock brake accumulator should be released by pumping the brake pedal till it gets hard or as specified in the service manual. After this bleeder screw should be loosened to allow old fluid to be flushed out of caliper bore. Any clogged bleeder screw must be removed for cleaning or replacement. It is cheaper to replacer sized caliper screw.
After reliving the caliper of the pressure, sized pistons be removed with caution by easing the piston from the bore by gently applying air pressure to the brake hose port while backing out the C-clamp screw. Since piston surface seals the brake caliper, if the piston is pitted or scored, it is better to replace it. Once the piston is installed, remove the caliper guide pins and lubricate them with caliper grease and apply thread-locking compound when the caliper bracket bolts are installed. It is better to always install new caliper hardware on the caliper bracket to prevent pad rattle and dampen pad squeal.
When the caliper is correctly serviced slide it smoothly on its guide pin or guide surfaces and should allow the rotor to turn freely when the brake pedal pressure is released. In case of caliper won’t release, the interior rubber of the brake hose might be peeling and blocking the fluid return to the master cylinder reservoir. Any misadjustment in master cylinder push rod or brake pedal height may be correctly adjusted, which is preventing master cylinder from releasing the fluid pressure from the caliper.
