Help please - Caliper slide pin rubbers 4L0

[richclare]

Hi guys,

I've managed to break the first slide pin rubber while rebuilding my calipers. I lubricated the orifice and rubber (nurse) and still couldn't get it to seat properly. It looked OK but the slide pin wouldn't pass through it, as though the rubber was too large.
Has anyone else had the problem and found a slippery solution

Cheers

Hello again,

Just did a search which I should have done before (sorry, frustration got the better of me!). LCBOTT said he had to trim the rubber. I've measured the hole compared to the rubber and they both measure 14mm diameter. Maybe someone has another idea from past experience?

They are a bugger to get in

I usually fit the rubbers and lightly grease before initially pushing the pins in one at a time (bracket 180 degrees turned)

Then once both pins have individually been pushed all the way home try and fit the bracket correctly with both pins

Too much grease and they air lock and won't go in

Thanks for your message Steve,

Since I posted, I have managed to get one in 😊. Firstly I trimmed the moulding lines off with a scalpel. Then I used a little washing up liquid and gradually pushed it into the hole with the end of a small screwdriver. I then used the blade of the screwdriver to push from the inside, of the rubber, into the recess. The pin was tight but passed through..... Still a real a**e to get in. Only 3 to go!

Thanks again for your advice.

No worries

Getting the boots to sit in the recesses can be a nightmare

Just to finish the thread.... the photo shows an old and new (top) rubber. The thickness of the part which fits in to the caliper is slightly thicker. I think a scalpel might be the best way to reduce it.
