Hey guys

I have a set of metro 4 pot calipers to put on my clubman, is a booster needed? Also where does the vacuum come from to operate the booster?

I'm not using a booster on my mini with 4 spot Minisport calipers and the brakes feel OK, not as easy pedal pressure as my Coopr S but much better than drums. Probably a Personel choice

I've got Metro 4 pots on the Moke with no booster and a standard m/c. They're very effective under normal braking conditions and extremely good if you really step on the pedal hard.

Cool thanks for the reply, probably won't go with one just needed some options to see if it needed one

Your choice of pads will also affect the pedal pressure needed. I use drums, but I hear that greenstuff pads are pretty good for a lighter pedal.

The vacuum needs to be taken from the inlet manifold, which means either modifications to the original, or a new manifold (which means a new exhaust manifold too). The original is a joint inlet/exhaust manifold, to replace one you need the other unless you cut the stock one.

A booster is never needed unless you have a particularly weak leg, or you live somewhere where the rules dictate it. It 's preference/feel thing.

I metro vented with greenstuffs. Put you through the windscreen without even trying.
