Title: Brembo radial master cylinder
Post by: xseal on May 14, 2004, 05:36:24 AM
What is the verdict on these? I've heard some racers swearing by them. What is the difference b/t the 19x20 and the 19x18 models?

19x20 has more power but less feel than the 19x18. My teammate got the 19x20 while I got the 19x18 and his brakes have WAY too much power. You can barely even touch them without going over the handlebars.

I love mine! Lots of power for my SV with the GSXR front end, while giving tons of feel. 1 finger braking all the way.

They are worth every penny if you are at the level to use them.

I am sure that Super Dave would agree with me when I say that there are a lot of other things that you should concentrate on to get faster (riding skill) before you get the brakes.  But, when you are ready for more stopping power, the Brembos will do the trick!

Well, brakes are good.  I wouldn't complain about that.

Really, if you can make the pull on the lever a little easier, you won't put so much input into the bars, so this can be a good mod that I wouldn't complain about.

But, like Edgar was talking about, be careful that you don't get the MC that gives too much...

Contact Geoff Maloney at GP Tech, LLC. (//www.gptechllc.com or geoff.maloney@gte.net).  Geoff know all about exotic braking components.  Give him a try.

Uh, I hate to sound completely ignorant here.  I've heard radial master cylinders are the shiznit, but how do they work and what makes them so superior over conventional master cylinders?

They have a larger diameter piston that helps by requiring less leverage and giving you more displacement of fluid, so the bike stops faster and you also get more feel than a regular setup. The pivot point where it presses on the piston is not located where it normally is, instead it is pointing towards the front of the bike, so the angle that the lever intersects it at is more like a "T". This helps with the amount of leverage needed.

They are also very adjustable thanks to a small knob that you spin on the front, which has something like 30 clicks of adjustability, instead of the usual 4 to 6.

Radial Master + Radial Monoblock Calipers = Ultimate Braking System, Period !  ;D

On the Brembo, the first number is the diameter of the piston, the second number is the distance from the lever pivot to the place where the piston connects.

The 19x18 has a 19mm piston and the distance from the pivot to the piston is 18mm.

The 19x20 has the same piston, but a larger distance from the pivot to the piston. Movement at the lever will cause more movement at the piston as compared to the 19x18.

I use the 19x18 on my SV.

Thanks for all the advice gents. I'm riding a well set up bike, but this is a post-getting the suspension right mod that seems to make sense. Particularly since the part will work on any bike.  I'm going to hunt for a good price and upgrade.

I have a 19x20 on my Ducati and it isn't too much wit  the stock calipers.  Now...if I had those monoblock radial mounted calipers...

any advice on the folding lever?  ie, does it work (fold rather than break)?  Its almost 50% of the price of the mastercylinder.

I can't tell you.  I'm using a Yamaha sourced Brembo master cylinder.  Everything is cheaper.  A little different, but it's more toward my small budget.

Everyone forgot the most important part of the radial master cylinder. It freaking looks PIMP!  ;)

is that good ... or bad?

Is that the cast or billet MC?

I just use the standard lever. I bought a backup.  They have a spot machined in them to cause just the tip to break off. I have seen broken folding levers.

I use the "short" lever on the Brembo radial I have on my motard bike (LP doesn't sell them, I got mine from Yoyodyne).  It doesn't stick out in harm's way as far as the standard lever.  It's still big enough to easily get three fingers on, if for some reason you need that many.  I think it's a better solution than the folding lever.

I also run handgaurds on that bike to save my levers  :P

good advice, I'm going with a 19 x 18 and a short lever.

Thanks.

I know some people that crashed hard and alot last year with the brembo master cyclinder and the standard, long lever. They never broke the lever, they always broke the internal plastic parts.  So, I just bought the rebuild kit.  It has all the parts to fix the master cylinder and only costs about the same as a lever.
