Yes, they (Team Stradale) replaced it thinking that exact same thing - did not fix the problem (and I actually inspected the old bearing and it seemed to be in good condition).

No, I have the fixed smaller brakes. To be clear, I have not actyually bled my brakes during sessions, only in between events. My local track, I cannot express how hard on the braking system this t...

It must be good stuff. When you do bleed, do you notice any tiny bubbles? For Radical, I have always used the Motul RBF 660. I always see two to four tiny bubbles when I bleed the brakes which is b...

That is what I meant. I mispoke. If the pedal went all the way to the floor you would have little or no braking. I was at the track last weekend with my spec racer ford. I had a similar experienc...

I think it would definitely be worth doing a full replacement then. I'm normally able to do it with a standard 500ml container of fluid (I use Motul RBF660) as long as you don't "overbleed" any one c...

@meatman - G'day Josh. Like Charley - I've never heard of anyone having issues like that, and certainly not to the extent that requires any bleeding to be done in the middle of a race event. These t...

@meatman That's certainly not my experience. I use Castrol SRF and typically only bleed brakes when I change pads (2-3 times a year) and/or rotors.

The spec from the owner's manual is Motul RBF 660. I would use that, starting with a full flush. The lifing schedule on master cylinder is 8000 km. If your foot is sinking to the floor, I would re...

Attachment : IMG-20230321-WA0004.jpg Hi! Im from Poland and I am an owner of Radical Prosport chassis 0082. I have tried it only once on a small track but I am already a big fan of it. I hope it ...

well, first time back on track in 2023 - a perfect day. Setup honed a little more, a shorter ratio (1 lower than factory standard), newer pads, and a lot more confidence to attack. Ended up doing 82 l...

@alex-heavens -G'day Alex, You noticed the threaded holes - Well spotted!... yes, will help get it apart without causing damage to the mating faces. I agree with your comment about first gear at idle...

Hi All, Just a bit more of an update on this topic.. I feel like I'm starting to understand what's required here. I now own three of these GDU's (one in the older RSX I have, a brand new one in the XX...

@rjbender That’s really interesting 👍 It sounds like Radical have ditched the oil cooler and replaced it with a heat exchanger for the XXR? Not sure about the 1st gear at idle part of the manu...

@charleyhradicalsportscarregistry-com many thanks, great info as always.

That is super helpful, I will begin diagnostics and resolution during my hot summer break now and get to know all these parts much better.
