Owners of other Hyundai or Kia vehicles such as the Accent, Sonata, Azera, Veloster, Tucson, Santa Fe, Veracruz, Genesis, Forte, Optima, Rio, Soul, Sorento, Sportage, i10, i20, i30, i35, i40, Tiburon, Avante and Sedona may also find these DIY instructions to be helpful.

The tools needed to complete this rear brake job include a floor jack, jack stands, a tire iron or lug nut wrench, a 14mm socket with ratcheting wrench, a Lisle 28600 disc brake piston tool.

Some compatible rear brake pads include the following with their part numbers: Wagner QC1544, ACDelco 14D1544CH, KFE KFE1544-104, TRW TPC1544, Bosch BE1544H, Wagner ZD1544, Bosch BP1544, Hyundai 58302-3XA30, and the Raybestos PGD1544C.

Then raise the rear of the vehicle with a floor jack and securely support it with two jack stands.

Spin off the five lug nuts and remove the rear wheel to reveal the rear brake caliper, bracket and rotor.

Pull the old brake pads out of the caliper bracket and make a mental note of where the wear or "squeal" bar is located.

On this 2011 Elantra GLS, the wear bar was situated at the bottom of the inner brake pad.

I recommend buying the Wagner ThermoQuiet QC1544 brake pads since they have excellent reviews on Amazon.

Remove the brake caliper slider pins from their rubber dust boots to make sure that they are well lubricated. If they appear dry, apply a generous amount of a high pressure / temperature silicone based lubricant or brake caliper grease.

Re-insert the lubricated caliper slider pins into the bracket and push until their rubber dust boots pop back into place.

Thoroughly clean off the rotor, caliper body, caliper piston and caliper bracket with some brake parts cleaner spray.

To help prevent braking noise, an optional step is to apply some CRC Disc Brake Quiet gel or any other similar product to the rear of the brake pads where they come in contact with the caliper. (Do not apply anything to the friction surface of the new pads.)

If your vehicle exhibits shuddering, pulsating, or vibrations during braking, you may need to have your rotors "turned" (resurfaced) or just replace them altogether with brand new rotors. If this is the car's first front brake job and the rotors appear to be in excellent condition, you should be able to just replace the pads with great results.

The easiest way to turn back screw-in caliper pistons is by using a disc brake caliper piston tool such as the Lisle Disc Brake Piston Tool (part # 28600).

Brake fluid is hygroscopic (absorbs water), so replace the brake fluid reservoir cap as soon as you are done turning back the caliper piston to prevent it from becoming contaminated.

Test fit the various sides of your disc brake piston tool, such as the Lisle 28600, to find the side that has the best grip on the piston. I found that the side with the four small nubs or pegs fit the best.

Attach a 3/8" drive ratcheting wrench with an extension bar to the disc brake piston tool and slowly turn back the piston in the clockwise direction until it is flush with the rubber dust boot.

Repeatedly check the brake fluid level in the reservoir while turning back the caliper piston to prevent it from overflowing.

Gently lower the brake caliper over the new pads and down on to the rotor. If the caliper won't fit over the new brake pads, you may need to turn back the caliper piston a bit more.

Line up the bolt holes in the caliper with the holes in the slider pins installed in the bracket.

Replace the two 14mm caliper bolts and thread them in by hand a few turns counter clockwise (as seen from the outside of the car) to prevent them from becoming cross threaded.

Double check that both of the caliper bolts are snug before continuing on to the next steps.

If your brake pedal previously felt soft or spongy, the brake fluid may be contaminated with moisture or the brake lines may contain air bubbles.

It would be best to bleed the brake lines at this time in order to flush out the old fluid and replace it with fresh DOT3 brake fluid.

Tighten the lug nuts a bit with the tire iron and then lower the vehicle from the jack stands using the floor jack.

Sit in the driver's seat of the vehicle and pump the brake pedal a few times to restore the brake line pressure. Then check the brake fluid level in the reservoir and verify that it is at the "MAX" line. If it is low, pour in some new DOT 3 brake fluid. Once the brake fluid level is correct, replace the brake fluid reservoir cap by twisting it on clockwise.

To properly break in your new rear brake pads, just drive normally for the first 200-300 hundred miles while trying to avoid any hard or "panic" stops which may glaze over the new brake pads and cause them to be noisy and/or not perform as well.

It's also a good idea to regularly examine your driveway for drops of brake fluid which may indicate a leak, check the brake fluid level in the reservoir, and also check that the lug nuts are still properly tightened.
