How do abutment clips work

Published Mar 29, 2026

A pair of abutment clips hold the inner and outer pads in place, preventing rattles and allowing the brakes to apply and release smoothly. If you’ve done your job properly, the abutment clips should fit into the caliper bracket lands without drama.

Do you need new clips for brake pads?

New brake pads usually come with new retaining clips. The clips may be specific to either the left or right side of the vehicle, so make sure that you are using the appropriate clip. Remove the old clips and replace them with new ones. They will easily snap into place.

Is brake hardware necessary?

A fresh set of hardware can gain horsepower and fuel economy by reducing brake drag. The constant heating and cooling of even normal driving will weaken your springs and anti-rattle clips over time. Weak hardware can result in excessive movement, binding, pulling, warping, uneven wear, noise, or other problems.

Are spring clips on brake pads necessary?

Brake pad spring clips (worn out example shown above) have two main functions when fitted, the first being to apply a light spring pressure between the caliper carrier and the brake pads – eliminating vibration which is the main cause of brake squeal.

Do you have to use brake hardware?

It depends on the condition of the hardware. If you can clean up the shims and retaining clips using a wire brush you can reuse the hardware. If the hardware is missing you will need to purchase a hardware kit. Putting brake pads on without the hardware will cause vibration and noise.

Where does the anti-rattle clip go?

The anti-rattle clips go on like this with the big tab facing the middle of the caliper. The hook in back of the tab goes under the pad holder. Start by feeding the tab and hook inside the caliper and carrier, then bend the inside side up and over to in between the pad and carrier like so.

What are the little clips on my brake pads?

The clips are designed to push the pad away from the rotor. This can keep the brakes cooler, reduce noise and extend the life of the pad. The clips fit between the pads and rotor and push the pads away from the rotor. These clips have more spring, while not preventing the movement of the caliper’s piston.

Do new calipers come with hardware?

Replacement calipers are sold either “loaded” or “semi-loaded.” “Loaded” means that brake pads and all hardware associated with the caliper and necessary to install it are included. … “Semi-loaded” calipers include all of the necessary hardware, but do not include the pads.

Can you reuse brake clips?

A 2016 study of brake clips and hardware reveals that reusing old clips can wear out your new brake pads prematurely, costing you extra $$ in auto repairs. … “Brake clips are the shoelaces of your brakes.” Well that’s what happens to your brakes when you replace your brake pads but reuse old clips.

Can I reuse drum brake hardware?

While brake hardware is often overlooked, it’s not the best practice to continually reuse old hardware. If it’s missing or bent from a previous job, the technician performing the service may not realize there was a problem in the first place.

Do brake pads include hardware?

What is in a box of brake pads? The typical box of disc brake pads has four pads (two pads for each side of the car). Some manufacturers will included other pieces of hardware to make sure the pad performs to its full potential. The items include anti-rattle clips, shims to reduce noise and wear sensors.

What happens if you don't replace brake hardware?

The radio hosts discussed how brake hardware, such as adjustment springs and abutment clips, often wear out but are not replaced which cause a variety of problems, the most common being brake noise. Brake drag, grinding, poor pedal feel and uneven pad wear are also common problems due to worn brake hardware.

What does the brake hardware do?

Brake hardware consists of all the supporting components in, on and around the calipers and pads that help properly align the brake pads or shoes and retract them away from the rotor or drum for smooth, reliable, quiet and efficient brake performance.

What is the purpose of the anti-rattle clip?

What is an anti-rattle clip? surface for the brake pad to move against. The clips may also have spring tension arms to keep constant pressure against the brake pad backing plate.

Why is a pad wear sensor sometimes used?

The wear sensors are designed to break or complete a circuit once the brake pad has worn enough for the sensor to contact the brake rotor. A warning light will usually light up on the dash, indicating it’s time for a brake pad change.

Which way does brake wear indicator go?

As a rule of thumb, the wear indicator should be placed so that it faces the leading edge of the spinning rotor. For example, on the drivers side, the wheel is spinning counter clockwise (as you face it), so the wear indicator is placed on the right side of the caliper.

Why do my brakes rattle?

When the brakes make a rattling or clicking noise, this is an indication that your brake pads need replacing. The rattling and clicking is caused by the vibration of loose components which damages the brake pad.

What is the purpose of shims on brake pads?

Brake Pad Shims: Pad shims on everyday passenger cars help reduce noise by providing a barrier between the brake pad and the caliper. The shim prevents small vibrations that build up to annoying noises when the brakes are applied.

Can I reuse brake pad shims?

In most cases, yes, you can reuse old shims as long as they are in good condition. You’ll want to clean them off with a little bit of brake cleaner and a rag or paper towels before attaching them to the new pads.

What loaded calipers?

Most parts stores offer a “loaded” caliper, which includes the brake pads, clips/pins, and other necessary hardware needed to do a brake job on your own. An Unloaded caliper is just the caliper and the piston – no pads or other hardware included.

Is replacing calipers hard?

Brake caliper replacement is pretty simple – until you get to the bleeding part. Then you’ll need a friend (and possibly a whole lot of patience) to finish the job. Fancy bleeder tools help as well.

Does Les Schwab do free brake checks?

We’ll inspect your brakes for free, take time to explain what we find, what’s needed to get them working properly, and provide a printed estimate.

Can brake hardware make noise?

Rattle or Clunk Noise: Brake rotor hardware can become dislodged from the caliper bracket and rub on the brake rotor, causing a noise.

What danger do the springs present when replacing brake shoes?

These return springs wear out and lose their tension over time. If you don’t replace the return springs during a brake job, the springs are at high risk of failure. Failed return springs will push the shoes up against the drum. This leads to rapid lining wear, brake drag and noise issues.

Can you sand drum brakes?

The brake friction surfaces must be kept clean. If the friction material on the shoes becomes contaminated with grease, oil or brake fluid, it may be necessary to replace them. If a small amount of sanding with emory cloth or 120 grit sandpaper will not remove the contaminant, the shoes must be replaced.
