This automotive maintenance "how-to" guide was specifically written to assist owners of the 5th generation 2011, 2012 & 2013 Hyundai Elantra in replacing the rear disc brake pads.

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 disc brake piston tool and a "C" clamp.

Some compatible aftermarket rear brake pads include the following with their part numbers: Wearever PNAD 1313, ACDelco 17D1157CH, Monroe CX1398, Raybestos PGD1157C, Bendix D1157 and Silencer Friction OR1157.

Rear Brake Caliper
The first few steps are to make sure the vehicle's transmission is in "Park", chock the front wheels, and slightly loosen the lug nuts on the rear wheels with a tire iron.

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

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

Use a 14mm socket and ratcheting wrench to loosen the two caliper bolts located on the rear of the brake caliper by turning them clockwise (to the right) as seen from the outside of the vehicle.

Remove Rear Brake Pads
Remove the two caliper bolts and carefully lift the caliper out of the brake caliper bracket. Rest the rear caliper on the suspension without stressing the rubber brake fluid lines.

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.

Remove Caliper Slider Pins
If your set of new pads came with new anti-rattle or "abutment" clips, pull out the old ones from the caliper bracket and install the new ones in their place.

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 "caliper pin grease".

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

Brake Parts Cleaner Spray

CRC Disc Brake Quiet Gel

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.

Use Side With Four Tabs
The '11-'13 Hyundai Elantra is equipped with screw in type rear caliper pistons that need to be turned back in order for the caliper to fit over the thicker new brake pads.

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) that costs about $10.

Turn Back Caliper Piston
Before you turn back the caliper piston, move to the engine bay and twist off the brake fluid reservoir by turning it counter clockwise. Removing the brake fluid reservoir cap will allow the brake fluid to more easily travel backwards through the system when you turn back the piston.

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 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.

Replace Caliper Bolts
Slide the new rear brake pads into the caliper bracket and push them together until they are flush against the rotor. Be sure to install the new pads with the wear bar located at the bottom of the inner brake pad.

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.

Brake Line Bleeder Valve
Use the 14mm socket and ratcheting wrench to tighten the two caliper bolts to just past hand tight or about 20 to 25 ft lbs of torque.

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. For more on this topic, check out my Brake Line Fluid Bleeding With An Assistant DIY Guide or alternatively the Brake Line Fluid Bleeding With A Power Bleeder Guide.

Lower Vehicle
Replace the wheel and the wheel cover (hub cap) before spinning on the five lug nuts by hand to prevent them from becoming cross threaded.

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

Check Brake Fluid Level

Replace Brake Fluid Cap
Progressively tighten the five lug nuts in a "star" or "criss cross" pattern to just past hand tight. It would be best to use a torque wrench or an air gun with a torque stick to tighten the lug nuts to about 80-100 ft lbs.

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. 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.
