So you want better brake on your R100GS, why not a 4-pot Brembo????

Sold Out

1st group before machining

Nice factory looking fit.

Brembo conversion for BMW R100GS-To convert the two pot caliper to a four pot Brembo caliper.
No modifications needed can use existing brake lines. I suggest Galfer Green Pads (FD198G1651) (FD 198G 1532 )and a braided brake line for best results.. Or pads of your choice which match up with K1100XX, R1100XX, R110GS or R1200C.

Caliper Only Price $190.00 ( $12 S&H )
Sales only to the USA
In purchasing buyer and/or user agrees to "fine print" below.

Personal check or money order OK Or Pay Pal add $9.00, to avoid PayPal fees pay as a gift or now I think it's choose send money to friend or family option. Contact me for how to send payment.

please read the fine print any questions about this or the calipers please ask.

The "Fine Print"

Please note-In purchasing caliper buyer and/or user agrees to the following- The caliper is a used modified part and it is the purchasers sole responsibility to check function of part and assumes all risk in it's use. Seller is not responsible for any for property damage monetary and/or other wise and/or bodily injury damage caused by brake caliper.

Brake Line Notes-

The stock length line is 31.5" (800mm) for 1989-1990), 25.75" (655mm) for 1987-1990.. I've purchased stainless steel brakes line from Rennsport Auto off Ebay for a decent price especially if you compare prices to Speigler or Goodridge Lines, but Motobins has a good price too.

Note it is best to terminate the flexible line at the steel brake line to the caliper as it keeps the flexible line behind the fork out of the way of getting snagged on something.

Master cylinder Notes-

There are two different master cylinders, the early style (1987-90) like on the R80 G/S in which the line threads directly into the MC and the later (1991-95) which has a banjo bolt which threads in.
Early MC bores- 1980-90 12mm, 13mm, 14mm, 15mm, 16mm (Motobins list all 5 bores), 12mm R80 G/S, 13mm R100GS
Late MC bores- 1991-95- 13mm

Brake Rotor Notes-

Over the years I've had problems with brake pads squealing, due to glazing of the rotor. A brake rotor hone will knock the glazing off and leaves the rotor a little roughed up. This is better than using sand paper.

A less expensive alternate to the stock BMW rotor is the EBC rotor. Ted Porter has had these at a competitive price.
