BREMBO MASTER CYLINDER INFO

Some random information on Brembo clutch and brake master cylinders. The sheet above contains some notes I made while researching which Brembo masters I should use. I originally started with a 19X18 clutch and 19x20 brake.

I quickly realized the clutch master gave too heavy a pull so I got a 16X18 which along with a larger diameter slave cylinder resulted in a low effort pull of the lever. This combo makes it almost effortless disengaging the clutch. Highly recommended!

The 19X20 brake is also the ideal setup. Easy enough effort, good modulation and moderate lever travel. The only reason I went with the RCS 19 this year is because I wiped out the nonadjustable one in a crash. The RCS can be changed from a 19X18 to a 19X20 by removing the small rubber plug in the forward facing position on the lever (which is folding) and turning a small screw. I haven't experimented yet with the two options but will report here when I have.

 Above: Disassembled Brembo 19X20 brake master cylinder. Bore= 19mm (off slightly because I was moving the calipers to get picture)

 (Above)  Lever pivot to piston center= 20mm

 (Above) RCS19- Bore 19mm, lever pivot to piston center 18mm position 1

 Red marking on piston actuator rod will show red when in correct location.

Lever to piston center = 20mm, position 2

 Adjusting screw is below rubber cap in lever.

 Original 19X18 clutch master. Very stiff pull.

Perfect 16X18 master. the 16 mm bores are the perfect setups for clutches on the Ducatis.
