Brake Caliper Sliding Pins

Replacement parts for front calipers

Lotus

The kit from aftersales (part no A100J6061S) is just for the seals, and one pack will do 2 calipers - i.e. it contains 4 seals.

If the sliders are worn at all, or any of the dust covers are missing, you are probably better off going down to HalFrauds and getting their vauxhall kit. It costs about a tenner each side, but includes the sliders, seals and dust covers for the allen head bolts.

The lotus part number for the same kit is A100J6066S, but costs lots more (and with delivery on top, it gets even worse).

How to re-grease sliding pins

1. Remove wheel
2. Remove caliper
3. Support caliper...
4. Remove sliders
5. Replace seals if required

Removing old sliders

The sliders are dead easy: push firmly on end of the first slider, it will pop past the dust seals. If the seal needs a helping hand, just lift the lip out of the end groves of the slider.

If the slider needs to be hammered or drifted out it's corroded. Support the caliper and knock 'em out anyway. Admire the oxidisation process and send the whole unit for reconditioning. New units come with sliders.

Putting in new sliders

Using your hands/fingers, smear Lithium Grease (White stuff) over the sliders and lube the bores, push the slider back through the first seal into the calipers and helping past the other seal. Using your thumb and forefinger the sliders should shuttle, a little stiffly at first, but then slide smoothly back and forth under a constant alternating pressure. Any excess grease will squidge out.

Don't be tempted to use graphite greases or a variant of copper eaze: these are very abrasive greases and will do harm to your sliders and the bores in which they sit. Silicon products won't perish the seals like other greases.

Repeat for the other sliders..
