Acura Tech Tip: Rear Brake Clunking Noise

Acura Tech Tip: Rear Brake Clunking Noise

The rear brake calipers clunk when you first apply the brakes after changing the direction of the vehicle. This is caused because the outer shims on the rear brake pads do not allow the pads to slide easily when you press the brake pedal. This causes the outer pad to hit hard during a change of direction, resulting in a clunk.

Probable Cause:
The outer shims on the rear brake pads do not allow the pads to slide easily when you press the brake pedal. This causes the outer pad to hit hard during a change of direction, resulting in a clunk.

Replace the rear brake pad shims.

Note: Brake pad replacement and disc resurfacing is not needed to get rid of the clunk.

Service Opportunities Still Exist With EVs

Like all ICE vehicles, you need the correct tools, parts and to follow the proper service procedures when servicing EVs. This video is sponsored by The Group Training Academy.

According to a recent survey of shop owners, less than a third of shops work on EVs, due to concerns about battery packs, inverters or other daunting technology. The good news is, though, tomorrow’s electric and hybrid vehicles still offer substantial service opportunities under the car.

Just as with conventional internal combustion engine or ICE vehicles, EVs are subject to the same traffic conditions, potholes, curbs and corrosive environments that can accelerate wear and tear on steering and suspension components. But there are also several other factors with EVs that can make life harder for the suspension.
