Grease For Slider Pins

[james250]

Can anyone recommend good grease to use to lubricate the caliper sliding pins? lexus originally have the pin lubricated with some sort of thick oily grey grease. It's nice and thick and not watery. I used carlube silicon grease for brakes, although it works and seems to lube it well, seems to be very runny and thinned out like watery.

you need something which is designed for high temperatures otherwise it will thin and potentially run out (and possibly make its way onto the disc/pads).

red rubber grease is a good choice.

LM2 (i think thats the name) is what I used when I replaced the slider pins on the RX a couple of weeks ago..

Lithium soap grease is the official stuff Lexus use, the comma lithium cv grease is the same thing.

Doesnt mention anything about being high temp

How much do you want to spend and what quality do you need?

Yes, that is the one.

not really a good recommendation though considering just about every vehicle suffers from corroded pins at some point

true enough... lol. Or maybe the trouble starts when someone decides they are going to use something else

I suspect the majority of the issues are due to the fact that in general, one pin is undone, the caliper pivoted up to get the pads out, new pads in, caliper back in place and pin bolt back in. No attention paid to cleaning and maintaining the pins and boots.

No attention paid to cleaning and maintaining the pins and boots.

but it isn't a specified maintenance item and the official maintenance manual instructions for changing the brake pads give no instruction to clean/maintain the pins either so you get the situation where they will just seize up at some point.

Even worse is it is more likely to happen if you get your vehicle serviced from a Lexus dealer than if you DIY or go to an independent who would perform some preventative maintenance.

The situation is potentially worse for hybrid vehicles which can easily go 60k+ miles on a single set of brake pads so even if you were to inspect when changing the pads the interval is probably too long to prevent corrosion.

Not sure what the actual root cause is, probably a combination of the boot not really preventing water ingress, not enough grease and maybe not the best grease for the job.
