Hello, 
 
I have an rb booster 2 bolt and i have no bite at all but as soon as i take it off the brakes bite is really nice and a nice squeek aswell. 
 
When its on its no noise and no bite but mint hold i would rather have good bite and good hold 
 
Im running heatsink yellows. 
 
could i make the booster less strong ? 
 
recommendations ?
