Can you put guide pins back in brake pads?
From there, you can re-insert the pins back into the caliper housing. They should slide right in if you used enough grease. Once those are back in place, you can complete the rest of your brake work — like replacing the pads and reinstalling the caliper.
Where are the guide pins on a caliper?
The caliper guide pins are two round metal pins on each brake caliper where the brake piston assembly sits. They’re called guide pins because they’re responsible for guiding the proper angle for how the brake pad meets the rotor.
What to do if your brake caliper pins are stuck?
Also, the pins could be stuck in the rotor or they won’t go in all the way after the pads have been replaced. The pins should be easy to take out with a screwdriver and a few light taps from a hammer. Caliper pin removal tools are also available at auto parts stores.
Where are the pads on a brake caliper?
Most brake calipers will have identical pads, you could use them inner or outer and left side of the car or right. However, some will have a specific pad for inner and outer. But be mindful some could also have inner, outer, left and right side of the car.
What’s the rubber on a caliper slide pin?
A caliper slide pin has a rubber boot that seals out dirt, and often has a rubber bushing for movement and support. If you’re not using silicone or PAG, these rubber parts can swell. [For more, check out Larry Carley’s article on Brake & Front End).
How does a disc brake caliper work on a car?
You press a pedal and friction pads squeeze spinning discs attached to your wheels. Simple. The genius is the design of a disc brake caliper, a crescent-shaped assembly of parts next to your wheel. When you brake, you push fluid into into the caliper, forcing a piston into a brake pad, and the pad into the spinning disc, known as a rotor.
What causes a brake pin to get stuck?
There are several possible causes. Something could be wrong with the brake line or piston. But often the problem is a stuck caliper pin. One or both of the little rails the caliper slides along — the caliper guide pins — get sluggish or seized. And that means your caliper won’t slide, and the outside brake pad won’t fully squeeze your rotor.
How can you tell if your caliper pin is stuck?
One sign that you’ve got a stuck or seized caliper is that your brake pads aren’t wearing evenly. The outer pad isn’t squeezing hard against the rotor, so it’s not wearing out as fast as the inside pad. In the video below, ChrisFix, a hugely popular mechanic on YouTube, shows the uneven wear on pads he took from a 2008 Honda Accord.
