How to Service Brakes

The brake system of your automobile can be one of the most important security systems in your vehicle. When you put pressure on the brake pedal, the wheel cylinder lifts fluid into the cylinder piston through the brake lines. This brakes activates the shoe or pad, which rubbers against the rotor or drum, and it slows down your car. You should check and serve your brake system every six months to keep it in order.

Servicing Disc Brakes

Loose lugs. While the car is on the ground, you should use a luge wrench or an impact wrench to loosen the nuts. Taking it in such a way prevents tires from rotating. This helps to make the luxury loose more efficiently and more safely.

Jack the car. Consult your service manual for secure jacking point. Slide the jack down the car and place it directly under the jacking point. Protect the car by making Jack stand up.

Remove the wheels. Now when the car has been lifted, the weight will not be on the tire. You can either remove the lugs by hand or with your wrench. Then, just slide the wheel away from the wheelbase.

You should always slide the wheel under the car. It adds an extra layer of security if Jack fails.

Detect Brake Caliper. Now when you turn the wheel off, you will see your brake rotor straight. On the rotor mounted (usually on the right side) you will see your brake caliper. The brake caliper has a brake pad against the rotor on either side.

Remove the brake caliper as a unit. Brake calipers are slightly different in cars, but they are always kept in place by bolts or clips. These are usually located above and below the caliper. Once the bolts and / or clips are removed, the caliper can be pulled away from the rotor. You do not need to disconnect the break line from the caliper, but you should pair it with a wire or cord so that it is not damaged or damaged.

Inspect the brake pads for wear or damage. Some brake pads have a groove in the middle that act as an indicator for wear. If the drain has almost gone, then the pad needs to be replaced. In any case, if the pad or inch is less fat or chipped or damaged, then it needs to be replaced.

Take care of any losses on the Caliphs. No need to replace your calipers, because they are designed to last for car’s life. It is being said, if the caliper is damaged, then it may have to be replaced. Apart from this, it is possible that the bolts or pins containing caliper may be damaged in the place. If this is the case then you have to change those people.

Take a closer look at the brake rotor. The brake disc, or rotor, is another important part of the breaking system. When the brake is applied, the pad presses down on the rotor so that necessary friction can be created to stop. It produces a lot of pressure and heat. If your rotor is not fat enough, or if they have grooves or chips, then they will need to be replaced.

The thickness of the minimum rotor is usually stamped outside the disk and can be measured using a micrometer, side caliper or tape semester. Micrometer is the easiest and accurate measurement.

Servicing Drum Brakes

Remove the wheels. The drum brake is located behind the wheel. Once the wheel gets out of the way, you will have access to the brake drum.

Remove the drum. By removing the drum, you will get access to the inner workings of your brakes, which are mounted on the backing plate. To do this, you will first need to remove the dust cap in the center. Below, there will be an intact walnut and cotter pin. To remove the nut, use the pliers to remove the coater pin and socket. The drum should now slide.

If you have trouble sliding the drum, check to ensure that there are no additional bolts or clips holding it on the hub.

It is possible for the brake shoe to be stuck against the drum. In this case, you will need to remove the rubber plug behind the backing plate to gain access to the brake shoe adjuster. Use a flathead screwdriver or brake adjuster bar to withdraw them.

Inspect the brake shoes. Brake shoe liners should not be less than the recommended minimum thickness. For the main break shoe (closest to the front of the car) it is usually around 1/8 inches. For trailing brake shoe (one closest behind the car) it is usually around 7/64 inches. Check your service manual for exact car specifications and replace any brake liner that meets that standard.

Identify and observe your return springs. After removing their feet from the brake pedal, these springs are responsible for bringing back brake shoes to their proper resting place. It is important that these springs are not damaged or loose. As long as the springs are still tight and not damaged or overly rusted, you can continue to use them.

If you need to remove the springs to replace them, or so that you can remove or change your brake shoes, make it air using the brake spring pliers.

Change your wheel cylinder. The best practice to replace the wheel cylinder is to stop the brake drum anytime. The brakes will continue to work until the cylinder does not leak or stick, but it is impossible to see the cylinder and determine how much to wear inside. To change the wheel cylinder, you must first remove the brake line with the wrench. After this, remove one or two bolts and remove the cylinder from the backing plate. Install the new cylinder bolt at the place where the original was, and then connect the brake line.

Inspecting and Servicing the Hydraulic Brake System

Find out the master cylinder. It is a reservoir tank which stores brake fluid. It is located under the hood on the driver’s side firewall.

Look for brake fluid out of the master cylinder. This will indicate that the master cylinder is leaking. It will result in very little brake fluid in the system and will reduce your stopping power. If not enough, there will be weak or spongey brakes.

Check your brake fluid. Hydraulic braking fluid is the medium which allows the force to move from the brake pedal to the brake. Remove the lid from the master cylinder and look inside. The brake fluid should be all the way up to the “full” line. If it is not, you will need to add brake fluid and follow any air-purifying technique that recommends your service manual.

Do not let dirt or other contaminated substances fall into the master cylinder. It will compromise your brake system. When your brake checks the fluid, change the master cylinder cap.

You should also change your brake fluid as often as your boss’s manual recommends, otherwise it can absorb moisture from the air which connects the system and reduces the pressure inside the brake lines by allowing the fluid to boil. 

Check your brake lines. If you have rubber brake lines, make sure there is no puncture, leak or fall along the entire length of the line. If you have metal brake lines, then you should also check for war or rust. If you see any of these symptoms of deterioration of the brake line, then you will need to change your lines.
