Although many car enthusiasts like to repair and maintain their vehicles, it may be difficult without the right tools. Common car maintenance tasks, for example, replacing parts of car brakes, such as drums, pads, and rotors, can be accomplished using ordinary battery powered wrenches and craftsman screwdriver sets. However, if you have a pair of brake spring pliers, it will be an easy task. Brake spring plieres are specially made for automobile braking work and consist of two useful ends. This useful tool is inexpensive and is a must-have tool for doing your own work. Learning how to use brake spring pliers can make your brake repair work easier and faster.
1) Purchase high-quality brake spring pliers at a local auto supply store.
2) Pull the car to a stable ground. It is important that when you park your car on a jack or jack support, do not let it sink or roll down.
3) Remove the hub cap from the wheel you will be working on. If any wheel you want to use has a hub cap, use a wrench tool or a micro screwdriver set to remove it.
4) Loosen the lug nut with a lug wrench or a cordless impact wrench. It is important to remember to loosen the lug nuts before jacking up the vehicle.
5) Jack up the car. After the lugs are loosened, it is necessary to lift the tires in order to remove the wheels.
6) Remove the wheel. At this time, the lugs may be loose enough to be removed by hand. If not, use a lug wrench or an air impact wrench to remove the lug. After removing the lugs, pull the hub out of the wheelbase. Put the wheel under the car as a backup protection to prevent the jack bracket from malfunctioning.
1) Remove the grease dust cap. The cap will be located in the center of the hub and can be removed by prying away from the hub.
2) Pull out the cotter pin. There is a pin on the front of the fixing nut to prevent the nut from loosening (called cotter pin). Remove it by straightening the bent end of the pin and prying it out of its hole with pliers or a screwdriver.
3) Remove the fixing nut. Use an electric torque wrench or ratchet to turn the nut counterclockwise to loosen it.
4) Check the drum. Some drums have small bolts fixing them on the hub. In this case, you will need to remove those bolts.
5) Try to remove the drum.
6) Retract the brake shoe. This step is only necessary if your drum is stuck by the brake shoe.
1) Remove the return spring with a pair of brake spring pliers.
2) Remove the retaining ring that secures the brake shoe in place. Gently grasp the outside parts of the retaining ring with pliers, push in and tighten until the retaining ring comes off.
3) Pull down the brake shoe. At this point, the shoes should be easily pulled away from the back panel. The bottom of the shoe will be equipped with another spring, but it is no longer tensioned, so you can slide it off the shoe.
4) Remove the emergency brake line. One of the brake shoes will be connected to the emergency brake line. To remove it, pull the spring cover back, and then slide the cable to the side to disengage it from the shoe.
1) Reinstall the emergency brake cable.
2) Remove all parts from the old brake shoe, and then transfer them to the new brake shoe.
3) Lubricate the backing plate. You need to avoid squeaking and friction of the brake shoes. Therefore, you should apply any bare or rubbed spots on the back panel.
4) Slide the bottom spring onto the new brake shoe. There is a hook at the end of the spring and a groove at the bottom of the brake shoe. Hook the spring into the slot.
5) Slide the show into place against the bottom plate. Now it's time to put the first brake shoe back in place. After alignment, fix it there until the fixing ring can be replaced.
6) Replace the fixing ring of the first shoe. Place the spring with the retaining ring on the small rod that protrudes from the rear of the brake shoe. Place the ring on the spring, then press in and twist until the ring slides over the rod and locks in place.
7) Slide the bottom spring onto the second brake shoe. Now it's time to install the second brake shoe. Similarly, you will start with the bottom spring.
8) Place the brake shoe in the correct position on the cushion plate. You need to align it with the adjustment spring rod.
9) Fix the adjusting spring on the second brake shoe. Here, you will use the flat end of the brake spring pliers to pry the spring into place and hook it on top of the second brake shoe. This will connect the two brake shoes.
10) Replace the fixing ring of the second shoe. Follow the same steps as the first retaining ring. Place the spring first, then push and screw the ring into place.
11) Tighten the adjusting screw with two screwdrivers.
1) Put the drum back. Slide the drum back onto the hub. You are about to rotate it and make sure it has only a little resistance.
2) Replace all bolts that fix the drum to the hub. You may not have bolts to secure the drum to the hub. If you do this, you should re-install them immediately.
3) Re-install the fixing nut and cotter pin. You need to tighten the fixing nut that holds the drum in place, and then pass the cotter pin through the hole to prevent the nut from loosening.
4) Replace the dust cap. The dust cap should be pushed back to the right. Make sure to snap it firmly into place.
5) Re-install the wheel. You should slide the wheel back onto the wheelbase and tighten the lug nuts so that the wheel is still in the position while the car is still on the jack bracket.
6) Remove the jack stand, and then use the floor jack to lower the vehicle to the ground. Do this slowly and carefully. You don't want the vehicle to fall suddenly.
7) Tighten the lugs to the specified torque. After placing the heavy object back on the wheel, use a lug wrench or impact wrench to tighten the lug to the appropriate torque specifications in the service manual.
8) If necessary, add brake fluid. When performing braking work, check the brake fluid and add more as needed.
9) Test the brake. Before driving, you need to make sure that the new brake shoes are working properly.
