Lack of Lubrication– Brake caliper bolts help the caliper adjust as the brake pads wear down.Shims are one of the more overlooked items when doing a brake job. Broken Shims– A shim that has worn out can make contact with the brake hardware and cause the grinding noise.If your Equinox’s rotors are warped they can make a grinding noise. As manufacturers have continued to find ways to improve fuel mileage, rotor materials are often thinned to improve unsprung weight. This problem actually happens more on modern vehicles.

Worn Rotor– If a rotor gets too thin, it can warp.Here are some other issues that can cause brakes to grind, but aren’t quite as common. Worn brake pads or a stuck foreign object are usually going to be the issue causing your Chevy Equinox’s brakes to grind. In this case, the debris will cause a terrible grinding sound when you press your Equinox’s brake pedal down. Foreign Object– It is entirely possible for a piece of debris to get lodged between the caliper and the rotor.If you ignore the squealing long enough, the brakes will run out of material and they’ll start grinding against the calipers. Sometimes they’ll even squeal without pressing the brake pedal at all. The brakes will squeal any time that you press them down. These squealers let you know that the pad is worn to a critically low point. Worn Brake Pads– Brake pads come with little pieces of metal attached to them called squealers.Squeaky brakes are typically an indication that the brake pads need replaced. Often, they’ll make your steering wheel shake when braking as well. Slowing down and stopping usually feels different when your brakes are grinding. Grinding brakes have a lower pitched sound than squeaking brakes. Make sure that you know the difference between squeaking and grinding brakes. Once the brake pads are worn all the way down, they begin to damage the rotors as you continue applying the brakes. Due to the nature of how brakes work (front brakes take more abuse), the grinding will usually be coming from one of the front brakes (but not always). Your Chevy Equinox is always going to have disk brakes on the front of the vehicle.

The number one cause of grinding brakes is going to be brake pads that have worn all of their friction material off. If the inboard friction surface of the brake rotor is notaccessible, reposition and support the caliper with the brake pads.Refer toFront Disc Brake Pads Replacementand/orRear Disc Brake Pads Replacement.Clean the friction surfaces of the brake rotor with denaturedalcohol, or an equivalent approved brake cleaner.Using a micrometer calibrated in thousanths-of-a-milimeter,or ten-thousanths-of-an-inch, measure and record the lowestthickness of the brake rotor at 4 or more points, equally spacedaround the rotor.Įnsure that the measurements are only taken within thefriction surfaces and that the micrometer is positioned the samedistance from the outside edge of the rotor, about 13-mm(½-in), for each measurement.Compare the lowest thickness measurement recorded to thefollowing specifications:īrake rotor discard thickness: 27.0-mm(1.063-in)Specification - Rearīrake rotor discard thickness: 18.4-mm(0.724-in)If the lowest thickness measurement of the brake rotor isabove the minimum allowable thickness after refinishingspecification, the rotor may be able to be refinished, dependingupon surface and wear conditions which may be present.If the lowest thickness measurement of the brake rotor is ator below the minimum allowable thickness after refinishingspecification, the rotor may not be refinished.If the lowest thickness measurement of the brake rotor is ator below the discard thickness specification, the rotor requiresreplacement.One of the most common problems with the Chevy Equinox (or any vehicle) is when the brakes are grinding.
