DIY brake pad replacement - how to change pads and avoid common mistakes

Your brakes are working, if done properly can save a lot of money. But the brakes work improperly done it very well if started with a professional work was paid more than the cost is. I am a master auto technician as a break in the last 25 years have hundreds of jobs in this article I will outline some of the basics. I also some common mistakes that beginners and professionals can also work when a break point.

Pulsating?

If the car shakes when brakes are applied, this means that the brake rotors are warped. Causes excessive side to side run out specifically to meet the car when stopping quickly from highway speeds. Rotors can be machined or them again until they are thick enough to correct resurfaced. If a beat or shake break, brake pads can be changed without the machining. In my experience, though, if machining or rotors are not replaced most of the time there will be a very short time after the excessive noise, squeaking a brake job, are. I machined or replaced by having them take care of the brake rotor by operating recommend.

Car Safe Lifting

Seems a little too basic, right? I place the jack stands for safety under the cars without having to have seen many people. Hydraulic jacks are great, but what if one slips or fails in some way, while anyone under the car work? I took quite a safe place with a jack stand can not emphasize the importance of having the car, just in case the car is for some reason. A jack stand under the car is very important for any work done under the car oil changes, starter replacement or any other work that a person could fail to crush the Jack likes to be. Once a mechanic in the house I was changing his starter to work with. Its hydraulic jacks was a slow leak and before he realized that the car gradually lower it, he was pinned under the car and could not get out from under it. Compressing his chest as the air, which limited her ability to cry for help to be allowed to breathe very shallow! Fortunately, a friend stopped by, saw what was happening and picked up the car. If it's fate could have a totally different result, his mistake may cost him his life.

Wheels, calipers, rotors and delete

After removing the caliper bolt wheels to find and to see what type of head bolt tool to determine what will be needed to check out. Common fasteners or the regular bolt head Allen or torx will. Usually two bolts holding the caliper and two caliper bracket bolts will hold. Usually just replace the caliper brake pads can be removed simply. An elastic cord or possibly damaging the caliper brake hose weight suspended to prevent something similar with the caliper. Be machined to the rotor has been removed or changed while most of the caliper bracket will need to be removed as well. Rotors or will just slide off or be held by the old style wheel bearings on setups. Most cars today will slide off the rotor. The design on the wheel bearings are not serviceable, meaning they are lifetime greased and only when they fail they like with oil during a break in the past may not work repacked to be replaced.

Pistons push

Brake caliper piston pushed back is required to install new brake pads. Piston brake pads wear out as slowly extends. That's a brake adjustment is required for disc brake system, it is basically self-adjust. Big channel lock pliers to the caliper piston back in the SEC can be. There is also a big brake equipment to be used in press can be used to push the piston back piston calipers in my favorite way to return. Rear disc brakes, like a piston wind back tool working on the 41 540 KD (DenLors of a best seller) usually need to turn to push the piston back in. Open the brake bleeder screw is recommended pushing the piston , it's easy to go back to it and allows for the possible loss of master cylinder prevents and / or ABS (Anti-lock brakes) or the system back to the old fluid forcing pump valves. Piston caliper bleeder valve immediately after the closing is pushed back will insure that the brake bleeding will not be necessary. If the caliper dust boots are broken caliper replacement is necessary. Broken shoes to allow moisture and dirt will enter the area around the piston and will cause it to stick or seize. Freeze or seize some caliper brackets above can also cause uneven pad wear is on the slide. Slides should be kept separate and silicone gel or disc brake oil lubricated. Slides freely brakes work properly to work to do.

Installation of brake pads and calipers

Left and right brake pads brake pads to take care of any potential differences. In addition there are sometimes differences in the inner and outboard brake pads. Obviously the friction of the brake pad to rotor part goes. My uncle a long time ago, before working on your Cadillac cars I've ever worked on a break started. I remember hearing that he put back the brake pads! He ruined my brake rotors. It seems like an impossible mistake, but when you do something you may be familiar with are are not. aftermarket brake pads, with most of the time his own noise insulators fit on the back of the pad will come up with. Some adhesive back to that, others can be built into them before setting the tab will be peel off plastic. Note that these are supplied, OE (original equipment) pad insulators will not be used again. After the pads are in place, be careful when the brake calipers hoses calipers no turning back, put on. Turn it on for them is a common mistake and hoses can kink.

Pump the brake pedal!

After everything is back together, it's time for a test drive. But first pump the brake pedal before putting the car in gear! Pedal to the floor will go and you could be headed for a crash if you do not. When the pump pistons are pushed out and pedal pedal is firm. There is an auto technician that I worked with a break after working brake pump forgot. He withdrew his service bay, when he hit the brakes the car was going and the car that was behind him went to rack up half way. The rear window of the car he was driving broke, luckily there was no other damage.

There are many types of brake systems, but most disc brakes are basically the same. Steps I have listed here should help to replace your brake pads after. But if you are not completely convinced, it is always a good a friend to help guide you through your first brake job is hands on experience is considered a question.
