Guys, is there a trick to fitting the dustseals (metal clip) in a S caliper?
I am really struggeling to get them to fit in.
I've tried tapping round but they just seem to big.
I've now put the rings in the freezer to see if they shrink a bit, but before I bugger them up even more I thought I'd see if there is any advice on here...
Thx

You trying to do it with the calliper still in one piece ?
If so stop messing about and split the calliper.

I always split the caliper and then press the dust seal into place by putting the caliper half between two squares of 1" thick hardwood in a vice.

They tend to go in with a painful sounding crunch!

Should have mentioned the caliper is apart, cleaned, plated and painted.

Graemec, I guess you do this before positioning the piston in?
(I followed the instruction and did oilseal, piston, dust ring)

No - usual order -> piston seals, piston, dust seal.

Leave the piston slightly proud, fit the dust seal to it and then press it all home.

In my experience many aftermarket caliper repair kits have dust seals that are VERY difficult to fit

A bit late now, but in the past I found going round the top of the bore with a hand held de burring tool to slightly chamfer the top edge helped a lot to get the retaining rings started into the bore.

Good to mention for future reference and searches Tom.
I thought of this but since the pistons were already in I didn't do this.
I would deffinately recommend this.
