R1/R6 + Thundercat calipers problem

[Danny]

I finally got round to cleaning my front calipers recently, but I came across a problem. Whenever I would squeeze the brake lever only one piston would come out at a time.

The top piston would always come out first, then if I held that one down the opposite one would come out and so on.....

I assume they are all supposed to come out evenly, so how do I fix it?

Hi

They should come out all at once, but rarely do. If you can easily hold the moving pistons in place so that they all come out easily then I would not worry too much. If you can push them in with your fingers then they are probably as good as you are going to get them.

All the best
