v8 Brembos | What's the correct way to spread the pistons?

TreyS · 11-15-2004, 02:37 PM

I had an old backing plate from a used pad that I used to spread the pistons out so the new pads would fit down in the caliper. I've somehow lost it and was wondering what was the correct way to install new pads? My way seemed kinda hokey but did work.

Thanks......

I just bought a $5 caliper spreader at the auto parts store

but some use a C Clamp or pry bar

How do you get the spreader down in there? I've used the C-Clamp and spreaders on normal calipers but these are too different for me to see using them here.

Big screwdriver and an old pad has worked so far but I often wonder if I'm damaging anything in the process like the dust boots.

Thanks.

Nope. Thats the best way to do it IMHO.

Use a big f'ing slip-joint plier and an old brake pad.

This is the proper tool. Although its a Porsche specific tool, it works universally on multi-piston brakes. Go figure. Expensive, but it makes quick work of pad changes in the pits.

PS, don't forget to select the proper width of your pads for the jaws.

Here's an older style that is a lil cheaper and a bit slower, yet should still work.

Thanks guys.

I guess I'll stick to what's been working so far.

Wonder if those are patented. Good business opportunity.

Just continue doing what you've been doing. Use the old pads (or current pads) as a lever. Works great and doesn't cost you a cent.
