How To Change Brake Pads And Rotors
What To Purchase For A Brake Pad And Rotor Repair?
The first items you will need to purchase is your brake rotors and brake pads. Most brake pads come with graphite grease prepackaged and often come with new brake clips. Sometimes the brake clips are optional and you can just clean your existing brake clips, or buy new ones. With brake rotors you have two options, you can purchase drilled and slotted rotors, these allow a cleaner brake pad as they get rid of the brake dust and allow better airflow keeping the brakes cooler, or you can just get the standard brake rotors that aren't drilled and slotted. Next on the list would be at least two bottles of brake cleaner and some anti seize, I personally like to use permatex anti seize. Make sure you have a torque wrench,socket set and a brake caliper compression tool.
Changing Brake Pads and Rotors Safety Precautions
Whether your vehicle be front-wheel drive or rear wheel drive, whichever brake you are going to be working on you will want to put a block of wood in the front of the vehicle or in the rear of the vehicle. If you're working on your rear brakes, place a block of wood in front of the front tire, if you're a working on the front brakes place a block of wood at the back of the rear tire. Once you've done that make sure your e-brake is engaged and you place the Jack & Jack stand in the proper location. You can see in the images for most vehicles there is a downward arrow showing where to put the jack. You will also want to make sure that you place the jack stand at good support point next to the jack.
Removing The Brake Caliper
Brake calipers come with two caliper bolts that are on the back side of the brake caliper, some of them also have a nut after the bolt that you need to use a wrench to hold it in place as you loosen the bolt. Remove the two bolts and pull the brake caliper off of the pads. Make sure to hang the brake caliper with a bungee cord/coat hanger, or set it on top of the control arm. You do not want to hang the brake caliper as it can put stress on the brake line. After you've remove the brake caliper just pull the brake pads out from the brake carrier.
Removing The Brake Carrier
Removing the brake carrier aka *(Brake Caliper Bracket) is fairly simple, once you remove the brake caliper, you now have easy access to the two brake carrier bolts that go through the spindle and into the brake carrier. Remove the two bolts, but make sure to place your hand underneath the brake carrier before you take the last bolt out or else it will drop and hit the ground. Take note of which carrier bolt go where, for most vehicles they are different lengths.
Removing The Brake Rotor
Before you pull the brake rotor off, most vehicles have a torx bolt installed, some vehicles are missing this and the brake rotor can come off without removing it. Look for the torx bolt on the side of the brake rotor close to the lug nut studs and remove it first if it is installed. Once you've removed your torx bolt, take a hammer and hit around the edges close to the lug nut studs with a to break the rust free. Do this if you are going to be replacing the rotor, if you are not you might want to be careful not to damage it. Once the rotor is loose you simply pull it straight off of the lug nut studs.
Depending on if you're working on the front or the rear brakes, with the rear brakes there are e-brake shoes that look like rear drum pads, go ahead and spray those down with some brake cleaner to get rid of the brake dust. It's also a good idea to take a wire brush and clean around where the lug nut studs stick out on the wheel hub. If there's enough rust it can cause your foot brake to pulsate in and out because the brake rotor is not flush with the wheel bearing hub.
Cleaning Where The Brake Rotor Used To Be
Removing Brake Clips And Slider Bolts From Carrier
To remove the brake clip from the carrier, simply put your fingers underneath the brake clips and pull up. Depending on how much rust is built up you may need to use a flat head screwdriver to pry them out. Once you remove the brake clips, head on over to the slider bolts on the carrier and make sure to pinch the rubber boot behind the slider bolt and then twist the slider bolt as you're pulling it out. Holding onto the rubber boot prevents the carrier rubber boot from tearing.
Get yourself a stainless steel wire brush and scrape the inside of the carrier where the brake pads clips would sit. Once you've done that go ahead and clean the brake pad clips or replace them with new ones. Next get a clean cloth and wipe off all of the old grease that is on the carrier slider bolts.
Cleaning Brake Carrier, Brake Pad Clips And Slider Bolts
Re-greasing/Installing Brake Slider Bolts And Applying
Anti-seize Paste On Brake Clips
Get yourself some Valvoline multi-purpose Grease and apply it to the clean brake carrier slider bolts. Once you've greased the slider bolts go ahead and install them back into the carrier, make sure that the slider bolts can go all the way flush. If the slider bolts push back out and are really springy because of trapped air, this can prematurely engage the brake pads. Next take the new or old brake clips and install them back into the carrier. Then apply anti seize where the brake pads slide on the brake clips.
