It has been my custom & practice to strip and clean car and bike brakes twice a year as a minimum, but these days I get my MOT place to do them on the car for me. It only cost about £16 incl. VAT for rears to be stripped, taken apart, cleaned & refitted just before winter. The MOT lad said there was no need, but the owners share my requirements of brakes. Besides which, if done regularly, everything comes apart easily.
The new s/s rear brake sliders on the CB500, machined and polished to mirror finish, as nagged by Mad Mike, were still in perfect condition 2 days before it was sold, after 3+ years all year use.
Thanks for sharing.
