Ok well after pulling off my old suspension last weekend I started planning my brake duct set up. Then I started to think about the pins that the calipers ride on. How often should the grease be cleaned and replaced? And what type of grease are you guys using? I just want to make sure that now that I'm on RA1's and am braking later (building more heat) that the brakes stay as constant as possible. This may be no big deal but I just want to make sure that I'm not overlooking something simple that should be done somewhat often.

Thanx for the input.

 

i clean and regrease them just about every time i change pads... it takes another 5 minutes and ensures them working... clean with brake cleaner and a rag, grease with regular old caliper grease from the local auto parts store. my stuff is green.

 

Every time I change pads I use wurth anti seize (either CU1800 or NI4200). I clean as much of the old stuff off and coat the sliders.

 

anti-seize on the sliders? seems a bit dry for the application...

 

Graphite = dry

 

I like to use a white lithium grease.

 

i use regular old wheel bearing grease.
something else to add to the 'list-o-chit' actually since i havent done it in a while

 

I guess it must not be that big of a deal. I just wasn't sure if there was a specific lube that deals with the heat, or if the heat caused any problems with the lubricant breaking down.

Thanx for the info

 

i use sil-glyde brake lubricant which is available in a 7oz tube at napa or little ketchup packets at autozone. search "sil-glyde" on the web for more info...

 

sometimes grease comes with new pads

My mechanical knowledge is somewhat limited, so feel free to correct me if I'm wrong about this, but... I thought the goop that comes with new pads is for applying to the backing plates to prevent them from squealing, not lubricant for the sliding pins in the calipers. No?

A. what does the backing plate have to do with brake squealing. (serious question, i thought the grease was for the slider pins.)

B. the only squealing i hear is from the pads and rotors, with race pads.

I've wondered the same thing, but it is legitimate (at least on street pads). I've always used this sticky spray stuff on the backing plate, and it does always reduce squealing. It makes absolutely no sense to me, but I've had like 50 different test scenarios that prove it.

 

I'm guessing that Honda high temp grease would work fine. That's what we use at work for the caliper pins.

 

Most common for the sliders is Silicone grease. If you want to go fancy, you can use Urea grease, we use this on clutch splines and pivots, and Honda calls it their Super High Temp Grease. You can find this stuff also listed as Synthetic Silicone Grease (not sure what that means) or Synthetic Brake Grease at auto parts stores, it is typically green in colour.

The Urea stuff is about $40 for a small tub from the dealer and is what I use on my own cars slider pins.

On the backing plate of the pads, you want a super high pressure lubricant to prevent squeeling, like a Moly paste. Noise is caused by friction during vibration. When you are braking, the pads are vibrating slightly up and down in the brackets. To eliminate any noise from this (this noise is typically only during light pedal application) you either glue the pads to the calipers (the sticky stuff you sometimes get with pads, this is also what the GM guys do) or you can put a high pressure lubricant like moly paste on the pads between the pads and the calipers to reduce the friction co-efficient between the two, and thus eliminate the noise, while still allowing the pads to move slightly to prevent seizing pads and grooving of the rotors.

Also, antiseize is a really bad idea for sliders. The carrier oil of the antiseize is petroleum based and will cause the slider boots to swell and eventually fail allowing water into the pins and seizing them. It also does not act as a lubricant, and the pins will bind under load. It also does not seal the boot seals on the pins allowing water in easier than silicone or urea.

So every oil change on my cars, I clean off the sliders, apply new Urea grease, clean off the backing plates of the pads and apply a very thin coat of molykote to the ears of the pads and to the areas of the backing plates where they touch the caliper and the caliper piston. And make sure the pads can slide easily in and out in the brakets.

EDIT: Just remembered this is the RR forum. I would not use the moly on the racecar, it tends to catch fire when it gets up to racing temp... I only use that on my/customers street cars. The racecar gets it's pads crammed in dry (LOL)

If you get OEM honda pads DO NOT use the moly paste for the slide pins!

It's to be used on the pads where they contact the caliper piston caliper and caliper bracket!

This stuff is pricey but will last a long time, I believe honda recommends using it on the transmission input shaft splines too. Also remember some pipe cleaners or similar to clean the slide pin hole on the bracket.
