Hello, I go through a fair bit of brake cleaner. I've been buying the motorbike brake specific stuff but was wondering if it was the same as any of the other cleaners like carby cleaner or spray on degreaser that are a lot cheaper from Kmart. It seems to be different each time, sometimes it smells like acetone sometimes ether and sometimes detergent. I know it's critical that certain chemicals stay out of break pads so I'd like to be sure I was using the right stuff. Cheers, Duncan. PS. I use a lot cleaning the pads/rotors between races on my mountain bike.
