There is the answer. What is your OE m/c piston diameter and lever pivot distance ? I did see in a post on here somewhere that laid out the maths that should help. Andy
T’internet says 4 x 32mm piston M4 monoblock caliper and the Brembo recommended upgrade for the OE m/c is the 19RCS corsa corta. Job jobbed mate. Andy
Just had another moment, we are talking track bike, yes ? The HEL m/c does not appear to have provision for the front brake light micro switch so you would need the banjo switch with a longer banjo bolt for the road. Andy
Morning gents. Again its a debate that can go either way as it can be a preference thing and I also relate to getting the best bang for buck. The RCS is a great product but does have a few minor issues - weeping bleed nipple is a pain, cast construction , it does however come with a micro switch. I have never used the Accossato PRS, but have heard people prefer these compared to Brembo RCS. The HEL master cylinder is new to the market (Released this month) therefore limited feedback. As per the HEL calipers. The build quality on both HEL products is excellent and the support (Cheaper spares) and warranty system is here in the UK and again quality, Simon the owner of HEL is passionate about his products and wants to see it at the top. I am fortunate to obtain sponsorship from HEL, hence the reason for the cheaper than normal price, I thought I would offer that to Forum members. On the flip side I don't want to be biased I'm here to be honest, if you purchase the Master Cylinder and on receipt don't like the unit I will refund bar the postage costs. That doesn't mean fit it run it and then decide it's not for you - same as every other purchase the item has to be returned in the same condition it was received. They are brand new and warranted by HEL. Many thanks Paul
It’s a stonking deal Paul. I’ve dealt with the guys at HEL and they are a first rate bunch. I’m keen to see if their range develops to support different calipers like the Stylema on my V4, in the fullness of time of course Andy
Hi Andy, Thanks for the kind words. HEL will fully back the product and are always trying to improve. I race with the HEL calipers and they are fantastic, constant, great feedback and awesome stopping power. And look good after a year of racing in all weathers. All the best Paul
Hi Yes comes as a19mm billet unit. Do you need any other details? Are you racing or for the road? Cheers Paul
Can’t wait to get this on and test it out at Portimao. Support from Paul on this has been outstanding.
@Pablo Pirate , I just wanted to update this thread, after purchasing a master cylinder along with the matching calipers and pads off pp. I have reserved judgment and comment on these until I had actually used them, I have them fitted to my 899 track bike, fitting came with a few problems as caliper spacing was a bit hit and miss and new brake lines were required , I also took the opportunity to upgrade the discs to brembo supersport spec to compliment the set up. First track day of the year on Monday and I can confirm this set up is epic, leaver feel is firm with no give in the leaver feel , brake feel was consistent and over the day I was braking later and later moving my braking points in every session without any drama at all, I made up so much time on the brakes it was quite remarkable , I am not a super quick rider and always judge my pace against my mate who is /was quick back in the day and I have never been able to run near him in the few days I have done, on Monday I was able to run with him no problem making most of my time up on braking. Great product and thank you to pp for sorting out the teething problems, great bloke
Thanks for the kind words and positive comments. If you need anything or help give me a shout and I'll do my best to help out. All the best Pablo
