I bought a caliper off ebay for $50.00 US and had a friend do the machining. Works great and looks stock.

I wouldn't say the Brembo 4-pot caliper conversion was "great" - my front brake was transformed from "very poor" to "poor" even though I'd also fitted a braided stainless steel line and an EBC floaring disc. With my R100GS-PD rebuild I have completely refurbished the brake master cylinder and the caliper with new seals and pistons so once it's up and running I expect a leap from "poor" to "average"

 

[(RIP) Arkwright]

The way to make a four pot Brembo work is to use a 14mm master cylinder (which you can't get for a GSPD, you have to bore out a 13mm and use a 14mm piston kit) together with Lucas TRW sintered pads, then you can comfortably 2 finger brake.

This at least is my solution to the problem, and works for me, no doubt there are others!

I put a 16mm on mine with the brembo 4 pot its one finger breaking I have one allso on a 13mm pump thats pulling it right in to breake bothe are still not a touch on my hp2 that has a 16mm radiel with a brembo 4pot and 320mm disc so I guese the biger disc helps !!!!!!!!!!!!!!!!!!!

Why do these calipers seize up ,took mine apart tonight and managed to get the offending piston out ,took the good side out and put it back in no problem cleaned the bad one up and even with the seal out it was tight the last 10 mm or so till it was fully home ,do the pistons get miss shaped or is it the caliper body that is the problem.

 

[DrFarkoff]

Mostly I think Salt gets behind the seal and presses the rubber against the piston making it difficult for it to retract

I don't like those bakelite things at all

Pete Keys was good enough to send me one and it's jammed solid on one side

I'm normally good at getting these apart but you can't grip the pistons at all

This is a mates K1100LT thats been run all winter without him knowing about getting in and flushing the callipers out

If you are careful and take your time they do clean up rather well

Ive been back at it and got it sliding in a lot better I think Ill get a stainless Piston from MW and the seals and a wee satchet of brembo lubricant for the wife .Thanks again Farkoff for the post

I think I'll be talking to a mate who has a lathe and buying a length of 316 stainless Just 6 inches or so mind

Should be enough for a couple of the wee buggers

There you go a wee business oporchancity ,was looking at the old piston and its chipped to feck so i,m gonna replace it anyway ,I,m a big hamfisted tit and I fooked the piston seal and lost the wee o ring that goes between the halves so gotta phone motorworks anyway .hope its the guy that knows his shit and sends me the right bits as I,m goin out a run on Friday ,need bits for thursday night.

 

[DrFarkoff]

Right they do list an o ring If they don;t have but you need it I'll stick one of mine in the post to you tomorrow

Piston is this but You'd be better with a pair

and seal kit is this LINK

EDIT If they have the kit the little O ring is in it according to the picture!
