There are metal discs attached to a vehicle.When the driver pushes the pedal, the brake pads press on the rotor, causing the wheels to turn slower.It also causes the disc to wear out and need to be resurfaced.The brake rotors may need to be replaced if they are damaged or worn out below a specified limit.Is that true?
Step 1: Put on gloves
It's a good idea to find a pair of sturdy work gloves before you perform any work on your vehicle.It's important to protect your hands from grease and dirt before you work on a vehicle.In the event of an accident, these gloves can protect your hands.
Step 2: The vehicle can be raised with a lift or jack on the ground.
The ground holds the wheels from turning if you use a jack to lift a wheel.The only way to prevent the vehicle from rolling is to block the other wheels.The parking brake may need to be released.It is easier to use a power impact wrench and/or a car lift if you use hand tools and a jack.For more information on lifting a vehicle with a jack, see the guide on how to change a tire.Jack only against a thick and sturdy metal part of the vehicle's undercarriage, if the jack presses into thin metal or a plastic molding, it could punch through, warp/bend or crack such surfaces.If a jack were to slip, support the vehicle on a heavy duty jack stand.Under stress, a scissor/accordion jack might break.A jack stand can easily be leaned over by pushing on the vehicle and it can fall.If you wanted to move a car sideways, you could jack up the side of the car with bottle jacks and push them until they fell over.
Step 3: The wheel should be removed from the vehicle.
To access the components of the brake, the wheel must be removed.Pull the wheel off if you want to expose the hub, rotor, and calipers.To keep track of the important nuts and bolts, many mechanics like to remove the vehicle's wheel cover and use it as a sort of "dish" to hold these small parts.Don't damage the hub cap on the ground.
Step 4: The calipers should be removed.
The bolts that hold the brake calipers in place are threaded from the rear of the caliper.You'll need a tool to reach these bolts.The bolts may have standard heads or Allen-head type bolts.After the bolts and any spring clips holding the caliper in place have been removed, hang it out of your way with cord or wire, taking care not to put tension on the brake hose.You can wedge and pry with a screwdriver or use a wood block and hammer to remove the caliper from the rotors and brackets.If you remove the caliper from the brake line, the brakes will start leaking fluid and need to be bled after the repairs to remove air.
Step 5: If necessary, loosen the bolts.
The brackets that the caliper was secured to can prevent the removal of the rotor in some vehicles.If so, use a tool to remove the bolts.Remove the brackets.The bolts may have a thread lock cement on them.
Step 6: Remove the part that holds the brakes.
It can be as simple as pulling it off.The wheel hub may be difficult to remove if the rotor hasn't been replaced in a long time.You can loosen it by using a hammer and wooden block.If you hold a block of wood against the rotor, hit it directly.The grease-packed bearings and the retaining nut must be removed from some wheels.The center of the hub or knuckle is where these are located.You may need to remove a metal dust cap, cotter pin or un-clinch a castle nut if you want the rotor to be removed.Don't get dirt in the bearing.The hub surface should be cleaned after the rotor is removed so that the new one can sit on the surface.
Step 7: If your vehicle has a grease packed bearing in the hub assembly, it's a good idea to replace it, since removing it will likely damage the grease seal and cause a potential failure later.
Step 8: The oil or protective coating needs to be cleaned.
To clean the new rotor, use a special brake cleaner solvent and a clean dry cloth.The performance of the brake pads may be damaged by oil, bearing grease, or improper solvent.If the brake pads are oily or greasy, they need to be replaced.
Step 9: Place the replacement on the wheel.
Put the new rotor on the wheel hub.You will need to thread the wheel studs through the holes.The wheel hub is where the rotor should be pushed back into.The castle nut and cotter pin on the hub assembly should be replaced at this point.If you bent the previous cotter pin to remove it, you may need to replace it with a new one.
Step 10: If you have removed the mounting brackets, you need to replace them.
If you disassemble your vehicle's mounting brackets, you'll need to replace them.Attach the brackets with the bolts you removed.If the bolts were used in an earlier installation, they should have a thread locker on them.
Step 11: The C-clamp or the caliper compressor can be used to compress the pistons.
There are grooves and a notch in the top face of the caliper pistons that can screw in.The pads and clips need to be put back in their proper place.Unhook the caliper from the out-of-the-way location and use a C-clamp or a specialized tool to compress the pistons.The caliper should fit over the rotor when the pistons are completely compressed.Since forcing brake fluid back through the lines can damage internal check valves or antilock brake mechanisms, many vehicles may require the bleeder valves to be opened slightly.
Step 12: The caliper should be re-installed.
If you want to place the caliper over the rotor, you need to make sure the slides are cleaned and greased, and that they have suitable brake pads.The bolts that were removed to take the caliper off of the rotor need to be reassembled.
Step 13: The vehicle's wheels need to be installed.
You're almost done.The only thing left is to lower the vehicle to the ground.Lift the wheel back into place.The wheel bolts have nuts on them.Carefully lower the vehicle to the ground.If you're using a jack, put it away.When the wheel is on the ground, make sure to tighten the lug nuts.To keep from bottoming out the master cylinder shaft, pump up the brakes using quarter strokes and refill the brake fluid.Make sure the fluid level is checked and top off as needed.If any of the brake lines were opened, Ibled the brakes.
Step 14: If you want to drive, you need to test the rotor.
It's a good idea to make sure the new rotor is working.Allow the vehicle to roll forward if you are in a safe location.The brakes should be pumped a few times.The brake pedal should be pushed down slowly.The brakes should work properly, with no loud noises, and the latter is a sign of worn-out brake pads.If you do a road test, the brakes should stop without any noises or pulsations.
Step 15: The pads need to be removed from the caliper.
If you don't have enough time, you may want to complete some optional brake maintenance.You don't have to repeat the process of lifting the vehicle, removing the wheel and so on.Later.When the notch on the brake pads is worn down, it's time to replace the pads.You can remove your old pads by sliding them out of the caliper.Some types of brake calipers hold the pads in place with a small retaining pin or spring, which will need to be removed before removing them.
Step 16: Remove the pins from the caliper.
The movement of the caliper is regulated by the slide pins on the outer edges.It's important to make sure the pins are well-lubricated.The slide pins should be removed with a properly-sized wrench.To remove the pin from the caliper, you need to remove a rubber boot on the slide pin.The pins will need to be cleaned and lubricated soon.
Step 17: The backs of the replacement brake pads need to be Lubricated.
A film of sealant can be used to help prevent the common brake problems of noise and vibration.It's important to be clear that only lubricate the back, not the front of the brake pads.If you use other lubricants, they can degrade over time or damage the brakes.
Step 18: The replacement brake pads need to be put into the mounting bracket.
The brake pads need to be installed.If your brake pads were held in place with a retaining pin, you'll need to replace them at this point.It's a good idea to wipe away excess lubricant from the pads.
Step 19: The slide pins need to be clean and lubricate.
The slide pins can accumulate dust over time, preventing them from sliding easily.If you want to lubricate the slide pins, you have to clean them with a fresh rag.
Step 20: The sliding plates need to be Lubricated.
Apply some lubrication to the brake pads.This will make it easier for them to move and reduce noise.Your brakes should now function like a well-oiled machine.You can either replace the wheel or do it yourself.
