How do I know if my caliper slide pin is bad?
Problems to look for include caliper pins that are corroded, or ones that aren’t properly lubricated. 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.
What condition does frozen caliper slide pins cause?
If the slide pins are frozen, the outboard pad doesn’t slide into contact with its side of the rotor. This means that the inside pad is doing most, if not all, of the braking. Not Good.
What do you use for caliper slide pins?
To lubricate slide pins, two types of brake grease are proven to work — silicone and PAG (Polyalkylene Glycol). That’s according to Gary Weber of Dow Corning.
Can you use regular grease for caliper pins?
This non-melting, synthetic grease can be applied on caliper pins, sleeves, bushings, and pistons to keep them lubricated throughout the lifespan of the brake pads.
Can you put too much grease on caliper pins?
Because the excess lubricant can melt or some chemicals can flash off. If excessive lubricant finds its way onto the caliper piston’s boot, the lubricant will attract metal particles that can destroy the rubber. too much!!!!! Shims need only a small amount of lubricant.
What happens if you don’t grease caliper pins?
Over time, the slide pins lose their lubrication and don’t slide the calipers so well. This lack of lubrication causes a few things to happen. While there is a rubber cover protecting the slide pins, they experience brake dust and rust buildup, which hinders the calipers from sliding.
Can you use white lithium grease on caliper pins?
You don’t have to remove the guide or lock pins to do this, but if you do, don’t use white lithium on them. You’ll need high-temperature grease specifically formulated for use with the calipers.
Can I use copper grease on caliper pins?
Never use copper grease there, and lithium grease can attack some rubbers/plastics.
Can I spray WD40 on my brake calipers?
WD40 should not be put on your brakes since it can reduce friction where it is needed and even break down and damage brake components. While spraying WD40 may temporarily reduce a brake squeal or squeak, it could also cause the brakes not to function correctly when you need them most.
