Corroded caliper slide pin & cracked dust boot...

[jonathancasey19]

Replaced rear pads and rotors today with Napa ultra premium parts. Passenger side caliper slide pin was corroded & dust boot was cracked.

With new pads and rotors already installed & bedded, I still need to replace the slide pin & boot.

Anything special to replacing these dust boots? Are they pressed in or what?

What is the best silicone based grease for the slide pins?

Thanks.

I just use anti a good moly grease or the silicone grease for spark plugs if it's super cheap at the check out.

Boot should just pull off the lip iirc and put a new one on.

Check out rock auto and replace all of them while you are there. A deep well socket and a few bumps with a hammer will get them pressed in.

The caliper is probably junk. Don't waste your time fixing it. Get a new caliper. They are cheap.

Caliper pistons work fine. I'm talking about the caliper slide pins and the dust boot which is attached to the caliper bracket.

What do you think makes the caliper move back and forth? Answer: The slides. I played that game before. Works fine for a few weeks than starts sticking again. Now if I see any corrosion at all, the caliper gets replaced. If it doesnt move freely by hand, its junk.

Are the front and rear caliper slide pins different?

The boots are the same but i am unsure of the pins. As long as you clean the bore well and dry any solvent with compressed air the will be fine. Boots should be replaced at every brake job if you want the grease to stay.

Carlson 16118 is the boot kit for one axle. Amazon or rock auto sell them cheep.

I usually use Syl-Glyde from NAPA. Good stuff.

The pins are different front to rear.

What's the best way to remove old dust boots?

 

[bmc1025]

Channel lock pliers. Stick one jaw inside squeeze the handles and wiggle.:spit:

Got it. C-clamp works best. Tore one boot trying to tap in with a hammer.

I use a hammer and socket.
