some capiler slide pin questions

[LMHmedchem]

Hello,

I have new rotors and pads that I will replace when the weather is reasonable and some suspension parts get delivered. I removed the calipers, plugged the hydro hose, and brought the calipers inside to clean them. I find that a wire brush wheel and a few Dremel-like attachments on a drill does a great job in removing all of the rust. It is surprising how well they clean up.

I also got new slide pins. I noticed that the lower pin was bound up and this was because the rubber vibration dampener sleeve had shifted out of the groove where it is supposed to sit. The set of brake pads I bought,

Power Stop Z23833 Z23 Evolution Sport Carbon Fiber-Ceramic Brake Pads

came with new caliper boots and rubber sleeves that look like they are replacements for the vibration dampeners. The sleeves, however, are somewhat shorter than the originals and also have large ridges that run the length of the sleeve. The originals are smooth with a spiral groove so I am not sure that these are the correct replacement.

I have read that the typical reason for the vibration dampeners coming loose is the use of a lubricant that is not rubber safe. I'm not sure what I used when I last did the pads and slides. It was probably the grease that came with the pads. I have read that Sil-Glyde is a good product and can be used to lubricate both the slide pins and pads ear/slippers.

So, a few questions.

- can I use the sleeves that came with the brake pads to replace the old vibration dampeners?
- if not, what should I use as a replacement?
- what should I use for a lubricant, if that was indeed the cause of the dampeners slipping?

Ew.

Semi-Metallic are the best for these heavy vehicles with undersized rotors...

Bendix Fleet MetLok or Wagner SevereDuty

I've always used black Lithium axle/wheel bearing grease on slide pins...

I have never had anything on this truck other than ceramic pads. I have Wagner ThermoQuiet on there now. The same was true for my Gen 1 as far as I remember, though that is getting to be a little bit ago. I believe that the Gen 3 came with ceramic on the fronts and semi-metallic on the rears, but I didn't buy my 2002 new so I can't say for sure.

I have never had issues with breaking and I think the ceramic pads have performed very well. I never tow anything and I only drive about 5,000 miles a year with this truck, so I am not exactly putting it through the ringer.

I am expecting that I should get a bit better braking with the hybrid PowerStop pads, but we will see.

I am concerned that the rubber vibration dampener sleeves on the lower caliper pins seem to have been damaged by whatever grease I used last time. I have been reading and the general recommendation seems to be to use a rubber safe grease on the slide pins,

CRC 05351 Brake Caliper Synthetic Grease ($13)
3M 08946 Clear Silicone Paste ($20)
Napa 7651346 SIL Glyde Silicone Lubricating Compound ($14)

These seem to be silicone based, but some contain molybdenum.

For the slippers and pad ears, most just recommend Permatex purple,

Permatex 24125 Ceramic Extreme Brake Parts Lubricant ($16)

though some report just using SIL Glyde or CRC on everything.

An interesting note, the Permatex 24125 listing on Amazon says, "suggested applications include disc brake caliper hardware, pistons, bushings, rubber sleeves and seals". The Permatex website also lists caliper pins but also clearly says, "for metal-to-metal contact only" which would imply slide pins that don't have a rubber sleeve. I find inconsistencies like that to be a bit annoying.

Use a caliper grease, white lithium will go fluid under braking temps, especially with ceramics.

The metal on metal doesn’t mean no seals. I’m quite sure all caliper slides are sealed. They’d never last without it.

I don't use the white lithium. I use the black that's used on axle bearings.

This is what I have on hand:

For many years and many vehicles I have been using Permatex ultra disc brake lubricant. No problems this far with the rubber boots. But honestly I have never even read the label.

Couple questions:
1. When you took out the caliper pins were the plastic/rubber sleeves soft and gooey or mostly hard and plastic like. They are supposed to remain hard and plastic like.
2. That special pin is on either the top or bottom on one side and on the other side the special pin with the plastic sleeve is on the other position. It's been a while since I've put new pads,but its easy to figure out,just take the pin without the plastic sleeve on it and insert it into both guide pin holes it should feel smooth in one hole and loose on the hole where the plastic guide belongs.If you are confused just remember they both DON'T go on the top or bottom hole
3. I went to O'reilly's and bought a small container marked CRC 05359 "Brake and Caliper Grease"" This one says right on the container " will not damage rubber or plastic components".
4. If your guide pin sleeves are rubbery.just go to the ford dealership and see if you can just buy a new pair of sleeves,or at worst 2 pair of guide pins.
5.If the dealership want silly money it shouldn't be too hard to find those parts at a boneyard

TechGuru, thank you for the reply. Your suggestions seem to be missing from you post, unless I am the one who is missing something.

1. When you took out the caliper pins were the plastic/rubber sleeves soft and gooey or mostly hard and plastic like. They are supposed to remain hard and plastic like.

The small rubber vibration dampener sleeves that fit in the notch on the bottom of one of the slide pins would not stay in the notch where they were supposed to fit. The were riding up onto the pin causing the pin to bind and jam instead of sliding smoothly. They were not "gooey" but had definitely stretched implying that they had softened.

3. I went to O'reilly's and bought a small container marked CRC 05359 "Brake and Caliper Grease"" This one says right on the container " will not damage rubber or plastic components".

CRC 05315 is recommended in many places for the calipers. It contains silica, graphite, molybdenum, and PTFE solvated in a polypropylene glycol ether. It is, as you say, rubber and plastic safe. I believe that CRC 05359 is just a larger size container of the same thing. I will probably go with this and see how it works.

4. If your guide pin sleeves are rubbery.just go to the ford dealership and see if you can just buy a new pair of sleeves,or at worst 2 pair of guide pins.

I ordered new slide pins from Raybestos since they are not expensive.

RAYBESTOS H5086 Caliper Guide Pin ($4.29)

These, however, do not come with the rubber sleeves for some reason. In my initial post, I mentioned that the brake pads I bought,

Power Stop Z23833 Z23 Evolution Sport Carbon Fiber-Ceramic Brake Pads

came with new boots for the slide pins and also with 2 sleeves that look like they may be slide pin sleeves (see the picture at the above link). The sleeves in the box don't look quite like those in the picture and have large ridges running along the sleeve. The originals are smooth with a spiral groove.

I will certainly replace the sleeves but I am trying to figure out if I can use those that came with the brake pads or if I need something else. I am wondering what others do when/if they need new sleeves.

Thanks for the tip about having the sleeve in opposite ports on the two sides. When I last changed them out, I just put them back where they had came from but I didn't really pay attention.

My browser blocks all script and content that's not first party. This is usually not a problem on a forum where I am logged in. I can see the pictures on your revised post.

Do you use the LubriMatic bearing grease on everything (slide pins, ears, slippers) or just the slide pins? I know I have allot of bearing grease around but I have never actually used it on anything other than bearings.
