6 lug brake pad change and grease

Changed my pads today due to some squeaks. There was still a good amount of pad left. Replaced them with Duralast Gold ceramic from Autozone. My question is I didn't use the included grease. Is it necessary? there didnt seem to be much grease at all on the back of the original pads. Should it have gone ONLY on the back of the pads or other points as well.

By the way, for the six lug, all you have to do is remove the pins and sliding bolts...you don't even need a wrench...just needle nose pliers to remove the cotter pins. I reused the original cotter pins since the Autozone ones were not a friendly shape. Absolutely no need to mess with the calipers except to compress them with a c-clamp. (I compressed with the pads still in place.)

 

Was it grease or was it anti-squeal compound? Toyota does put a little anti-squeal compound on the back of their pads from the factory. You don't need much.

If it was grease, I usually clean and grease the sliding bolts. Brakes that hang up cause all sorts of problems, so it's cheap insurance.


Also, it's a good idea to pull the caliper, if only to better inspect the dust boots for the pistons. Over time they fatigue, rot and crack, allowing dirt and moisture to get in there. That can rust/score the cylinder bore, which means a $30 rebuild turns into an expensive caliper replacement.


I'd go back in and at least grease the sliding bolts.

 

are you getting any squeal in reverse when applying the brakes? just grease the slide pin holes. I would not mess with caliber pistons. I changed my brakes at 97k miles and would of gone another 20k.

Which is why they were squeaking.

 

The packet said "organic grease". I'll go back and grease the sliding pins...the ones that have the cotter pins at the end of them, correct?

I'm still getting some squeal from the brakes. I might as well grease the back of the pads as well...

 

Pick up a little packet of silicon brake grease. its about a $1 at the parts store. Only needs to be where contact is made.

 

The $1.50 silicone brake grease packet from AutoZone did it...I think. Just went out for a test drive--no squeal. Should have saved some time and lubed the first time. Lesson learned.

 

Been there.

 

Still have the squeal. It's most noticeable at low speed, crawling with the brake depressed almost fully. I'm not sure if I should apply another packet of the brake grease. I had sprayed brake cleaner on all surfaces prior to appyling the grease.

Could it be a problem with the rotor surface? It's just annoying. At least now I know my brakes are in good shape and the pads are lifetime replaceable from AutoZone.

 

when I replaced my pads, the new ones, wagner thermo quiet, rode a little lower on the rotor than the factory pads. took a dremel to remove the rust toward the center where new pad rides. may not be what is causing the squeal but it might be. I also replaced the slide pins, can buy them at Autozone cheap. used the old and new anti rattle clips, top and bottom.

the squeal comes from a vibration of metal on metal. Need to lube what ever moves that is metal on metal on the caliper.
