A) Information 1. Purpose a. The purpose of this instruction is to save you money by replacing your own car breaks at your home. b. Depending on the mechanic shop you may go to, you will save from $80 to $120 by changing your own breaks with this instruction. 2. Required Tools a. b. c. d.

4. Terminology a. Lug Nut- The type of nut that holds the tire onto the vehicle. (most vehicles have 4-6 lug nuts per tire) b. C-Clamp- A type of clamp in the shape of a “C” which will be used to compress the caliper. c. Caliper- The cylinder device that compresses the break pads onto the rotor when you press the break pedal in your vehicle. d. Car Jack- A lifting device used to lift vehicles off the ground enabling you to fit underneath the required part of the vehicle.

e. Break Pads “Pads”- Made of composite metal, they are forced against the rotor by the caliper and cause high friction which causes the vehicle to stop. f. “meat”- The composite ceramic that makes up the break pad. As the breaks are used the “meat” is worn away. g. Tire Iron- The “L” shaped piece of metal containing a socket at the end which fits the lug nuts and is used to loosen them. h. “Break the seal”- An action using the Tire Iron where the lug nuts are just loosened approximately 2 turns. i. Load bearing member- A part of the underneath of the vehicle that supports most of the weight of the vehicle and is made of thick steel. An example of load bearing members are the frame rails.

B) Phases Car Placement 1. Car Placement Place car in a flat clear area.

*Caution*- If you do not have any flat ground around your home you must go to a location that is flat. You should never jack up a vehicle on any ground that is not flat and even. Lifting a car up with a jack is dangerous and can potentially cause harm to the individual working on the car if safety precautions are not taken. Safety precautions include but are not limited to: ensure ground is flat, ensure car is in park, and place bricks or other big objects in front and behind both back tires to prevent the vehicle from rolling off the car jack. Remove Tire 1. Loosen Lug Nuts

Take the tire iron and remove the hub cap. Use flat end and place it around the outer edge of the hub cap. Pry the hub cap open with tire iron and remove it with hands. Take tire iron and “break the seal” of all lug nuts on that tire.

Hub Cap Lug Nut

Remove hub cap “brake the seal” *Note*- The reason of “breaking the seal” before the tire is lifted up is because it will take a good amount of force to break the seal and it cannot be done if the tire off the ground. 2. Jack Placement Place jack under front frame rail.

Frame Rail

Release mechanism

*Caution*-Placement of the jack is important. It must be on a load bearing member.

*Note*-Make sure that the releasing mechanism is twisted tightly to the right to prevent the jack from inadvertently lowering. Raise the jack by pumping the handle. Continue raising the jack until the tire is about a ½ in off the ground.

*Caution*- Never place the jack on joints or on the engine. This can result in damaging your vehicle. The best location is on the main frame of the car or frame rail itself. 3. Remove Tire Remove the lug nuts by hand. Remove the tire and set is aside.

*Note*-They should be loose from the initial loosening, but if they are not, then use the tire iron. Remove Brakes 1. Inspect Brake Pads Inspect brake pads.

Rotor

Brake pads

*Note*- Inspect brake pads to determine if replacement is needed. Inspection includes determining how much meat is left on the pads and if any other parts are in need of repair. If the meat is less than 1/8 in thick the pads should be replaced.

2. Remove/Loosen Caliper Take 14mm wrench and loosen the caliper bottom bolt. Remove the top caliper bolt.

Top bolt Top bolt

Bottom bolt Bottom bolt

*Note*- The purpose of loosening the bottom bolt and removing the top bolt is so the caliper will rotate. This allows you to rotate the caliper out of the way and remove the pads without completely removing the caliper. 3. Remove Old Pads Move caliper out of the way by pushing it out towards the front of the vehicle.

Pull off the old pads by hand.

4. Clean Rotor and Caliper Clean rotor and caliper with compressed air.

*Note*- Cleaning the area from old dust helps the break pads work better and prevents squeaking. Install Brakes 1. Install New Pads Take new brake pads and place in location of old pads.

Aligns up

*Note*- The brake pads have a slight curve to them to fit the circular rotor. Make sure the pad curves around the rotor. The top of the rotor and the pad should align up. 2. Open Caliper Take C-Clamp and compress the caliper.

*Note*- Compressing the caliper causes the caliper to have more depth thus allowing the larger new brake pads to fit. 3. Re-install Caliper Lift up caliper back to original position. Reinstall upper bolt and tighten both bolts.

Install Tire 1. Install Tire Lift tire onto bolts.

Tighten Lug Nuts Tighten lug nuts by hand.

2.

Tighten lug nuts with tire iron. Follow a 5 part star pattern and repeat 4 times.

3. Lower Jack Place jack handle in jack release mechanism and slowly rotate counterclockwise.

Release Mechanism *Caution*- Rotating the release mechanism too quickly can cause the vehicle to come down too rapidly and could cause damage to the vehicle or injury to the person operating the jack.

4. Torque Lug Nuts Torque lug nuts by tightening them with the tire iron.

*Note*- After tightening the lug nuts by hand, use your foot and tap on the end of the tire iron. Your legs are stronger than your arms and the lug nuts need to be fully torqued. Replace the hub cap and repeat steps 2-15 on other side tire.
