Could take more than that, try using a c-clamp and work the caliper piston back and look for any leakage if you have money get or rebulid your caliper. Take a piece of sandpaper and using a swirling motion lightly sand the rotor and make sure it doesn't have high or low spots in it.
My main mistake was not retracting the piston properly when replacing the caliper. Brakes work now, but still get an occassional 'whistle', ie high pitched rubbing noise when driving (NOT braking).
Any ideas? FYI the pads are a bit worn down and I will have to replace them soon. Could this be a factor?
Thanks. The thing is that originally the noise was whilst braking. Since I had the caliper off, the noise is when just driving. It stops when braking and for a few seconds after. The pads are down to 2mm (1mm listed as min). They are not hotter than the other sides' after a 10 mile run. Still confused. Trying to avoid taking it to the shop.
