Last Updated March 25, 2022

Brakes are the most essential safety feature of any vehicle, so only fix them yourself if you have the correct tools and enough confidence to do the task well. You can learn how to change the brake pads and rotors yourself in no time at all. Equally with about of the really of import parts of the automobile, the blueprint of the brakes hasn't changed much in years, which is expert because once yous learn how to supervene upon the brakes you lot can utilize that knowledge to all cars old and new.

How Brakes Work

The brakes operate using a unproblematic hydraulic system that transfers the pressure y'all apply to the pedal onto the restriction pads and rotors. When you button down on the restriction pedal, a lever pushes a piston into the master cylinder that'southward filled with hydraulic fluid. This fluid is and so squirted forth pipes which feed another cylinder positioned next to the brakes to complete an hydraulic system that multiplies the force yous put into the pedal.

With some cars you'll know the instant the brakes need changing because you lot'll need to apply them earlier than normal to terminate for the corner but with other cars that's not so obvious, particularly if you're used to driving a truck with different loads in the dorsum and on dissimilar road surfaces which mean you suit your driving manner to friction match the condition of the road and the weight of the vehicle. When the restriction pads wear down, you'll start to hear a squeaking noise whenever you try and slow the vehicle. Thankfully some newer cars have brake pad sensors that alarm the driver when the pads demand replacing.

Preparation

According to home services websites, the average cost of changing pads and rotors on a typical machine is $324. That varies from state to state but yous can expect to save part of those costs if you do the work yourself. To begin the job y'all'll need to buy new brake pads and rotors. When you get home, put the machine in brake then brainstorm the job by loosening the lug nuts. At present raise the jack and and so residuum the machine on jack stands.

Replacing the Brakes

Now remove the bolts from the caliper and slide it out. Now remove the bolts on the rear of the hub that keeps the caliper carrier in place. Y'all might need to whack the rotor with a hammer to go information technology off. Do whatsoever it takes because y'all don't demand the old rotor anyway. Now use a wire brush to remove rust from the hub before installing the new rotor. Then yous replace the caliper carrier bolts and you'll exist ready to shrink the caliper piston. Do this until the piston is affluent with the housing of the caliper. To complete the job, install pads in the carrier and use some grease on the exterior of the pad for smooth operating.

To Stop

Put the wheel dorsum on and tighten the lug nuts to consummate the job. Although you've got new pads and rotors on the vehicle, you'll hear some squeaking to begin with. That's normal when y'all've changed the brakes. To become rid of that, drive on a highway at around threescore MPH and then gradually decrease speed to 40 using the brakes. Practise the same from 50 to 30 MPH a few times and and so just bulldoze effectually and use the brakes as normal. Y'all'll soon discover the dissonance go away.
