How To Remove Brake Caliper Slide Pins

Wondering what the sleeve on the lower brake caliper bolt does? This commodity reviews what the lower brake caliper bolt'south slide pivot prophylactic is and it's purpose.

Why Is In that location a Rubber Sleeve on the Lower Brake Caliper Bolt?

If you lot have ever had the pleasure of doing a brake job on a rusty car before, you take probable encountered the technology nightmare that is known as a "lower brake caliper slide bolt." Now, if you have erased this hardware-laden retention from your encephalon, or aren't familiar with this style of bolt, I'll do my best to aid out.

This is the type of bolt that doesn't desire to come up out of its pigsty considering rust has essentially fused information technology with the brake caliper subclass. Information technology's the bolt that gives y'all a few hope-filled turns with a pipage-extended, half inch bulldoze ratchet, and and so crushes your dreams when it becomes stuck solid for absolutely no logical reason. It's the threaded evil that requires a chisel and sledgehammer to remove when the ratchet fails to do its ane chore. Yep. That'due south the bolt we're talking about here today.

A Theory: The Restriction Caliper Slide Pivot Rubber Is an Anti-Rattle Device

If you have ever successfully removed this bolt (which non many have in the Northeast), you know that it has a rather cute footling rubbery sleeve on the finish of it every bit if to mock each one of your herculean removal efforts. The upper caliper commodities does non have this beautiful safe sleeve, so why in the globe did the car manufacturer put one on the lesser caliper bolt? The truth is, I don't have an answer for that. However, I have spent quite a few late night hours in search of the truth, and I'm now hither to share with you the one theory that makes the most sense to me.

These cute piddling rubber caliper bolt "sleeves" (that'southward the most common name for these) are anti-rattle devices for the calipers.  The sleeve provides additional friction, which prevents the restriction caliper from rattling/chattering within the confines of the caliper bracket. Information technology works similarly to a shock absorber, where it slows down and dampens the movements of the calipers.

As long every bit the whole system stays rust-gratis and lubricated, it'south truly a uncomplicated and effective organisation. Yet, when that rubbery sleeve prevents the caliper commodities from sliding, or rust begins pulling the vehicle back into the earth, all bets are off.
