ACCOSSATO MASTER CYLINDER CNC BILLET - PRS LEVER - 16mm BORE

The PRS CNC Billet master cylinder, features Accossato's patented PRS adjustment system - Now with a choice of natural anodising or black anodised body - feature: adjustable lever ratio, with a cammed pivot pin, to keep the Pushrod perpendicular with the piston, for reduced side loading, drag, and increased feel and performance, unlike competitors adjustable ratio master cylinders which move the pushrod out of alignment when the ratio is adjusted.

CNC machined from a single piece of solid 7075 Alloy billet. the CNC machining process allows for super critical tolerances, to give superior sealing properties, which particularly show up during hard track use. the Lever is adjustable for distance from the bar, and also lever length (the lever is segmented, segments can be added or removed)

We at TBR have tested a large variety of master cylinders, from all major brands, with championship winning racers in the UK club circuit scene, and this is not only the best performing master cylinder in it's class, it's is the best value for money

We recommend the 16mm bore master for single disc monoblock caliper systems, with pistons above 34mm diameter

• The differences between a forged master cylinder and CNC master seem insignificant on paper, but are clear on track. There is NO dead lever travel with these master cylinder, the system is pressurised as soon as the lever is pulled with no slop in the system.
• There is little to zero fade under extreme use - as brake fluid temperature goes up, it's viscosity goes down, and this makes it harder to keep the system fully sealed and pressurised - this is the cause of the common complaint of lever feel getting softer as the race goes on. To combat this, quite often we will see track riders/racers, sacrificing feel, by fitting a firmer lever ratio to the machine - this master cylinder remains constant from lap 1 until the finish, and thus allows a softer lever ratio, more power and more feel without the downside of excessive lever travel

Note:

Aftermarket master cylinders use a different thread pitch banjo bolt, to OEM master cylinders, remember to add one to your order if needed!
