front brakes

[el1gordo]

hi

i have an 95 xj600 and I am gonna attempt to change the front pads,armed with a haynes manual and little bit of expeirence.

The Haynes recommends using Shin-Etsu G-40m sillicone grease on the pads and calipers.I was wondering if anyone knew of an 'equivalent' that I can use.

Thanks

Copper grease on the back of the pads and around the pins they slide on.

I was gonna get some copper ease on my next jaunt to Halfords.

Careful with lubricants...

Copper grease on the back of the pads if you want to - it "may" help stop the pads squealing. I don't believe in it so don't bother. It is definitely worth using copper grease on the pad retaining pin for its anti-seize properties.
Do not let copper grease or any other mineral oil based grease near any rubber seals. The mineral oil content will swell the seals. This means if you put mineral oil on the pistons, it will get on the dust seal, which will swell and seize your caliper. If you put in on the sliding pins, the rubber boots will swell and seize your caliper. Use only silicon grease anywhere which may contact rubber seals. Just go to your local motor factors (ignore halfrauds, they are silly expensive for this type of stuff) and pick up some silicon grease. Also known as electrical compound (because it keeps corrosion off without making insulation swell/go brittle) and sold as red rubber grease, coloured for easy identification but its the same stuff.

Short version: no mineral oil on rubber seals!

Indeedy - I always use a very light smear of copper grease on the back of the pads, but in my experience brake squeal is more often caused by either calipers full of brake dust of ridging on the discs.

thanks for the warning amorti.
