Should brake caliper pins be greased?
Not lubricating the guide pins: Caliper guide pins on floating calipers should be cleaned in solvent and new grease should be applied. The grease is under extreme heat and pressure so always use a caliper specific grease. NEVER put a torn boot back on a car.
What is the best lubricant for caliper pins?
Our pick for the best brake caliper grease is the Mission Automotive Dielectric Grease/Silicone Paste/Waterproof Marine Grease. It’s waterproof and seals and protects various components, including brake caliper pins. For a more budget-friendly option, consider the Permatex Ultra Disc Brake Caliper Lube.
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.
Why do you need to remove the sliding pins on a disc brake?
Video tutorial on how to remove and lubricate the sliding pins on a disc brake assembly. Sliding pins, also known as guide pins allow your caliper to float, so when your brake pedal is applied, the braking surface on both sides of the rotor can be used.
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.
When do you need to check brake caliper guide pins?
You’ll need to inspect the brakes like you’re about to change the pads. In fact, it’s a good idea to check the pins whenever you’re changing the pads yourself. Lift the car, remove the tires, take the caliper off and look at the caliper housing. See those pins at the top of the housing? Those are the guide pins.
