For any vehicle as heavy as a truck, the brake system is very essential to its reliability, which is conferred to it by truck brake pads. Brake pads are situated inside the wheel configuration. The function of the brake pads is to stop the vehicle when the brake is applied by clamping on to the rotor, whose torque is converted into heat when the brakes are applied. The trucks are heavy vehicles that take use more force to stop. With use, the brake pads become thin and need replacement. Many conditions contribute to wear and tear of the brake pads like quality of the installed brake pads, driving conditions and driving habit of the driver.
Step 1 – Raise the Truck
Use the floor jack and jack stand in combination to raise the truck off the ground. Keep the height of the truck convenient enough to remove the wheel and access the rotor.
Step 2 – Remove the Wheel from Axle
Loosen the screws and lugs to remove the wheel from the axle. The rotor, brake discs and calipers can be seen clearly. Clean the dust on the brake system assembly with the rugs. Caution: do not breathe brake dust as it can contain asbestos.
Step 3 – Remove Caliper
For removing the caliper, loosen the Allen bolts on the caliper using the appropriate allen key/wrench. Loosen up each bolt one by one before removing the caliper. Once the nuts are loosened, slide off the caliper from the rotor.
Step 4 – Remove the Old Brake Pad
Now is the right time to remove the brake pads from the caliper. The caliper has a piston that holds the brake pad with the help of a clip. Unclip the brake pads and remove them.
Step 5 – Depress the Caliper Piston
This step is very crucial to replacing the brake pads as it opens up the space in the caliper clogged by the piston. Use the clamp to remove the pressure off the piston to push it back into the caliper. Now is the time to insert the new brake pads that are much thicker.
Step 6 – Place New Brake Pads
Use brake cleaner material to steer off any kind of dust or dirt on the brake pads. Insert the new brake pads into the caliper after applying some high quality grease which offers stability at higher temperatures and decreases any chance of a squeaky brake system.
Step 7 – Re-Mount Caliper
Put the caliper back on the rotor very carefully. Tighten the Allen bolts using the wrench. Use the brake cleaner one last time, to ensure that there is absolutely no particulate matter in between the caliper and the rotor. Now, depress the brake pedal and rotate the disc to check for proper free rotation. By pressing and depressing the brake pedal, pressure is restored into the braking system. Make sure that the brake fluid is level or topped up.
Check the brake pads are working fine by rotating the wheel and applying brakes. Take the car out in a quiet area to gently wear the brakes in. By performing this task oneself, it is possible to save a lot of money over time.
