Last Updated March 25, 2022

Brakes are the most essential safety feature of any vehicle, then only fix them yourself if you have the right tools and enough confidence to do the job well. You can larn how to change the restriction pads and rotors yourself in no time at all. As with most of the really of import parts of the car, the design of the brakes hasn't inverse much in years, which is skilful because in one case you learn how to supercede the brakes yous can apply that knowledge to all cars old and new.

How Brakes Work

The brakes operate using a unproblematic hydraulic arrangement that transfers the pressure you utilize to the pedal onto the brake pads and rotors. When you button downward on the brake pedal, a lever pushes a piston into the primary cylinder that's filled with hydraulic fluid. This fluid is so squirted along pipes which feed another cylinder positioned side by side to the brakes to consummate an hydraulic system that multiplies the force you put into the pedal.

Knowing When to Replace the Brakes

With some cars y'all'll know the instant the brakes need changing because you'll demand to apply them before than normal to stop for the corner but with other cars that's non so obvious, particularly if you lot're used to driving a truck with different loads in the dorsum and on different road surfaces which mean you lot adjust your driving mode to friction match the condition of the road and the weight of the vehicle. When the brake pads habiliment downward, yous'll first to hear a squeaking noise whenever you try and slow the vehicle. Thankfully some newer cars have restriction pad sensors that alert the driver when the pads need replacing.

Grooming

Co-ordinate to home services websites, the average cost of changing pads and rotors on a typical car is $324. That varies from state to state but you can wait to save part of those costs if you do the piece of work yourself. To begin the task you'll demand to buy new brake pads and rotors. When you get home, put the automobile in brake and so begin the job by loosening the lug nuts. Now raise the jack and then residue the car on jack stands.

Replacing the Brakes

At present 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. You might need to whack the rotor with a hammer to get it off. Do any information technology takes because yous don't need the old rotor anyway. At present use a wire brush to remove rust from the hub before installing the new rotor. And then you replace the caliper carrier bolts and you lot'll be set to shrink the caliper piston. Practice this until the piston is flush with the housing of the caliper. To complete the chore, install pads in the carrier and utilize some grease on the outside of the pad for smooth operating.

To Finish

Put the wheel dorsum on and tighten the lug nuts to complete the task. Although you've got new pads and rotors on the vehicle, y'all'll hear some squeaking to brainstorm with. That's normal when you've changed the brakes. To get rid of that, drive on a highway at around 60 MPH and and so gradually subtract speed to twoscore using the brakes. Practise the same from fifty to 30 MPH a few times so only drive effectually and use the brakes as normal. You'll before long notice the noise become away.
