Improved Brakes

I have never been happy with the Brakes on the GSXS - in theory should be great with Brembos but for me no bite and not confidence inspiring

Today
  • New Brembo Levers with Radial Master Cylinder
  • HEL brake lines
  • EBC HH brake pads

Huge improvement - more bite, firmer lever, more confidence

I was under the impression you have to be careful with upgrading the master cylinder because of the ABS?

My guess would be the ABS unit would release line pressure so how much flex is in the lines or how that pressure is applied wouldn't make a difference? But that's just a guess.

I thought the problem was the uprated master cylinder would overpower the valves in the ABS unit? Might be wrong

Hadn't thought of that. That would **** up the ABS! Maybe look at which other bikes use the same ABS unit and which masters they use?


Edit: sorry to jump on your thread PhuketPaul. Sweet looking setup, I'm sure it feels much better and I'm sure the bosch ABS is up to the task

Gixerkev, you are on the right track.

What matters is the relationship of the pistons (brake calipers) and the piston int he master cylinder.

The calipers here use 4 32mm pistons. Of course, its times two because theres a right and left caliper.

I would be pretty confident that if these two were matched up properly, it would not put any extra stress on the abs unit.

I could tell you how I did all kinds of sophisticated math formulas to do this, or I could say I copied what brembo recommended, and found a ducat master cylinder to complete it with.

On this caliper and master cylinder set up (stock) its not bad, at all. The stock brake pads are very mild. Ebc are ok, but Vesrah makes a far better pad for this caliper.

If you use something like this, you wont need a master cylinder. Sure, it would be nice, but you dont need it.

Ducati's which always get great reviews for their brakes use the same Bosch ABS, same callipers and the brembo radial master cylinder.

They feel much better now

You bought the good brembo master, didn't you? Yours is the rcs 19, isn't it?

If so, which setting do you like best?

I bought a used mastercylinder, form ebay, and it was a Ducati take off.

Perfect ratio for what I need, but not adjustable , likeyours.
