Hello, fellow M109R owners. I just recently powdercoated my front and rear calipers. I took the calipers totally apart by removing seals, pistons, nuts, bleeder valves. etc. The place I took them to sandblasted them and covered piston port holes, bleeder valve holes, etc. I put them back together with new Suzuki Brand seals and pistons and bolted them back up. I bled the system by the book, left caliper first, right caliper second, rear caliper kept an eye on the reservoirs to make sure it does not get empty, pressed the brake lever a few times, opened and closed nipples. I still have no pressure on the brake lever and when I looked at the front calipers while my friend pulled the brake lever, the pistons are not moving. Is there something I am not doing. ALSO, spoke to someone who stated that it is NOT good to powdercoat our calipers because the calipers in the front are aluminum and the oven baking heat warps the inside of the piston port. Anyone ever heard of this? Need advice and help.
