Hi All. In the middle of doing the front brakes on my TS. They are the twin piston verada calipers.

In the Gregorys workship manual I have it states to re-grease the guide pins if required.
If they came out with grease on them and there is still grease in the hole that they sit in do i need to regrease them?
Also the manual states to use a "silicon grease" ONLY, I have a silicon spray but not grease. Would spray be okay or is it completely different from grease?

Secondly the used pads that I just took out had some kind or fluro red grease or glue on the back of them. Mostly on the pad that the pistons make contact with but also some remants of it on the back of the pad that sits on the front side of the disc. Do i need to apply this same "stuff" to the new pads before installing them?

Lastly according to the manual (parts diagram for twin piston caliper) I should have one shim on the outside pad. There was no shim when i took the pad out. Is this a big issue? or is it fine to install new pad with no shim?

First time doing brakes on this car so let me know if my terminology is wrong.

Thanks

Lliam

Not an expert. But the bright red grease you're talking about might be anti-seeze or anti-squeal. Unless its smeared all over the contact size of the pad I wouldnt worry too much. Somebody will correct me if I'm wrong.

Greasing the slider? I'd do it if the grease appeared overly contaminated and gritty, or if it was a little light on or nearly dried up. Not exactly which grease to use though?

The shim issue is another thing I'm unsure of also, but I like everything to go back together the way it came apart. I've replaced pads on both cars and I'm sure one set actually came with fresh shims while other brands didnt supply them. My approach at the time was that if the guy making the pads wanted me to have shims he would've given me shims. Right? Well, to be honest I'm not sure I'm right in thinking that way. I see you can buy "shim kits" so... maybe?

super vague answer, sorry chief. I'm hoping somebody here helps out as I think I could benefit from the answers also :P

Clean the guide pins thoroughly, and the hole it slides in. Use silicon grease, also called "rubber grease" as it will not react with the rubber boots on the guide pins. Makes the brakes so much smoother.

Original twin piston calipers have shims to stop rattle and squeal, some people throw them away and use the red gluey stuff for the same purpose. Not a good idea. Each pad has 2 shims, they also stop the tangs on the pads from wearing the caliper.

New pads don't come with shims, you are meant to reuse the ones you got. Get some from the wreckers, any TS with ABS will have the same twin piston calipers.

There are 4 shims and 2 wear stoppers. Feel free to swear at the person who just threw them away.

I have seen the rubber grease at some auto stores. This stuff here: http://www.pbr.com.au/products/replacement/ancillary.shtml
I was going to buy some but then I get mixed stories when I search the net (other car forums), people saying it can be used no worries then others saying its not the same as silicone grease and don't use it.

What would you use to clean the bolt and hole? Brake cleaner, degreaser or just water? Would be worried about using something too strong that would damage the rubber boots.

Are you sure thats the diagram for the twin piston caliper Mad Max? It does show 4 shims in the diagram i have for single piston (Gregorys manual) but the the twin piston diagram is different and only shows a single shim on the outside pad. Either way I am missing shims that i should replace. I checked the passenger side, missing on that side aswell.

Thanks for the info.

Not a good idea max? Riiiggghhhttt.....

For starters there is nothing wrong at all with using the "red" stuff. In some cases is better than a set of 15 year old shims which are bent up

Grease use lithium grease as does not dry out

Well I was thinking that obvioulsy I havn't been runnning shims for a number of years and have had no issues with the brakes (not even squelling or shuddering). Was going to go ahead and just find out what the red stuff was and put the pads in without the shim but thought i would ask here first since it is my first time doing this.

I may drop by the wreckers this morning and see if I can easily find a set of good condition shims (need to get some other stuff anyway), if not I will just get some of the anti squeal red stuff.

Thanks guys.

Well job is done now.

Went and got the shims from the wreckers. Also got some of the CRC "red goo". Put both the shims and the red goo on just to cover all bases.

The car and I are still alive after first test drive. Did some fairly hard stops and she seemed all good. Was a tiny amount of smoke coming of the brakes when i got back but I assume that is just excess whatever burning off the pads and rotors.

Now the rears next.

I removed my shims years ago because the brakes were "clicking"
The orange/red gooey stuff works a treat.
