how are working formula brakes? did you solve play on bushing?

[@mtbboy1993]

I solved it by upgrading the levers to Rgtec levers, no more dead throw, you can find them on Ebay.
The levers have bearings. You might need to sand the original pin, I had to even more than the manual suggested, it was not only the edges, I lubed and sanded and tried to insert it, I repeated until it fit all the way trough.
The bearings don't have play. But there is still a bit up and down okay but that's due to lever moving up and down in the lever pivot. Maybe the lever could have been a tiny bit thicker. But tha t would have to be miniscule as there sonly 1 mm play, in total, so around half mm top and bottom. Leve removes has pivotal play of around 2deg. This is due to the pin it self is moving up and down. I can't tighten it more to prevent the up and down play. The pin is basically a female axle othe ris a bold that threads into it. So unless machining custom bolts I can't solve that. Don't know if aftermarket options exist. Bu tit works well enough. This play was there when brake seere new too.
The lever action is much smoother with bearings, even when the brake was new.
The holes add grip without being too sharp, comfy but grippy. Well machined.
I got them from Ermg shipped from Germany but he's out of stock so buy directly from Italy on Ebay if you want it, I got standard length but long and short exist too.

Here's more info about the brakes.
I had to rebuild the front caliper due to leaky seals, this is why some of vids had noisy brakes, they wae deformed, they were shamfered, so this eventually causes stuck pistons, they did not retract consistently. But rebuild with new seals solved that.
The bleed port seals let air in on both front and rear, so needed new o ring on both, but wear was inconsistent, I bled rwa brake multiple times and it was worn let a bit of air in, but front brake the seal was shredded horribly, after just one bleed. So seemed like faulty seals or some contamination causing damage. But the brakes are working now.
A nice thing with these brake sis you can get all pasts as spares. But can't buy O-rings seperately only with bolt. But hardware stores might have correctly size.
The brakes work in at least - 10c buy th elever feel is more wooden, and more sensitive, as in more grabby. But not a issue.
I did not get a chance to test colder temps than this.
I ronlu used them with Formula mineral oil.
