How To Replace Calipers

are you hearing noise while driving awhile breaking do you feel vibration in the pedal or steering wheel when you slow down does the vehicle pulled to one side when driving it even more when breaking these are signs that you may have brake caliper problems in this video will go over the basic steps and replacing a caliper since we'll be working under the car it's important to observe basic safety precautions wear a dust mask and I protection to protect yourself from brake dust do not use compressed air to claim brake parts always use a spray brake cleaner to keep brake dust from becoming airborne park the vehicle on a flat dry surface and make sure the parking brake is not engaged talk the wheels and place automatic transmissions and park and manual transmissions in neutral before beginning gather all the tools and supplies are needed so that they'll be within reach when you do the job when jacking the vehicle insured the Jack is rated for the weight of the vehicle being lifted and use factory live points which can be found in your owner's manual once the vehicle is lifted support the vehicle on Jack stands and not the Jack most vehicle manufacturers recommend replacing calipers in pairs for maximum performance and even where since they work together to stop the vehicle this assure safe efficient breaking work on one wheel at a time using the other will for reference snap a photo of the system or better yet have a vehicle repair manual handy while the vehicle is still on the ground loosen the lug nuts just a little on the wheel that you'll be working on once each lug not has been loosened left the vehicle with the proper Jack and supported on Jack stands once you have the vehicle on Jack stands remove the lug nuts and we'll next thoroughly clean the break host a caliper fitting with a cloth before disconnecting to prevent contamination to the brake fluid now disconnect the brake hose fitting at the caliber there are two types of brake hoses one with a banjo bolt and the other with standard threaded fittings at the host has a threaded and connecting it to the brake caliper loosen or disconnect the flexible holes from the brake line on the frame and first remove the retaining clip holding the holes the frame or bracket then separate the holes from its mounting and disconnected from the brake line fitting this will prevent the brake light from twisting and possibly getting damaged now unscrew the hose assembly at the caliber cap or tape the open brake line and or caliber inlet port to keep dirt from entering the system and prevent brake fluid loss next remove the pans or bold securing the caliper to the mounting bracket then let the caliper off the rotor if the original caliber can be removed because the brake pads are held tightly against the rotor apply a little pressure to the brake pad to push the piston in just enough to allow the caliper to loosen up for removal a rubber mallet can also be used to tap the caliper off the rotor but care must be taken to prevent damage that can occur at the calipers hit too hard now that the caliper has been removed detach the brake pads and hardware from the caliper and set it to the side this is a good time to inspect the area for leaks and check for cracked or worn hoses we can now install the new caliper remove the caliper bolts sliders and rubber boots from the %HESITATION caliber and inspect them for damage take a moment to clean the caliper melting points and the slights check bolts and pens for pitting and rust check boots for tears and brittle this if any of the hardware appears to be worn or damaged replace with new hardware properly Lou bolts and sliders with silicone lubricant and apply loop inside any rubber boots or bushings be careful not to get Greece brake fluid or other contaminants on the brake pads over the brake rotor as it could affect braking before installing brake pads into the new caliper make sure the caliper piston is compressed completely then install any Shams clips or pens that were removed from the %HESITATION caliper onto the replacement for front calipers most of the time you can simply press the piston into the caliper by hand but occasionally it requires the use of a C. clamp if the C. clamp is used place the %HESITATION pad on to the piston and apply force to the center of the pad for rear calipers the piston needs to be screwed back into the caliper this can be accomplished by using a special break tool that can be purchased at your local AutoZone check your vehicle repair manual for specific instructions after applying synthetic break lubricant to the backside of the brake pads installed the brake pads into the caliper taking care to avoid shipping the brake pad edges then reinstalled over the rotor take care not to cut or damage any dust boots that are installed and torque the mounting bolts to the manufacturers recommended torque S. torque requirements vary from vehicle manufacturer to manufacturer referred to the vehicle repair manual for exact specifications if the brake hose that was removed had a copper gasket install a new gasket and reconnect the brake line to the caliper recruit the brake hose in its frame mount or bracket with the retaining clip and tightened holes in on the caliber first followed by the frame and second before reinstalling the wheel bleed the brakes to ensure there is no error in the system and the brake system is working properly be sure to use new clean fluid for more information on how to bleed the brake system see our video how to bleed the master cylinder and brake system once the brake system has been bled reinstall the we'll tighten the wheel nuts by hand until they are as tight as possible and then snuck them down with a ratchet and socket with the wheel still off the ground complete this process one not at a time going in a star pattern around the tire one not across from the other Jack the vehicle off the Jack stand and remove it from the under the vehicle with the Jack stammer moved slowly lower the vehicle to the ground without applying the full weight of the vehicle on the tire using a torque wrench tighten the wheel nuts to the required torque specification once again repeating the star pattern tightening procedure and when all nuts have been completely tightened lower the vehicle all the way to the floor remove the Jack and repeat the process for the rest of the brake system that you're performing the brake job all once the job has been completed checked the brake fluid level add fluid if needed then start the vehicle impress on the brake pedal a few times to prime the system once the brake pedal feels firm removed the wheel chocks and test drive the vehicle to insure the brakes are working properly stop by
