Avoid fitting new brake discs and pads at the same time. New pads should always be fitted with old discs and new "green" discs with old pads. Why? Because with use, discs form a heat-hardened surface allowing them to bed in new, solf pads. Similarly used pads will also become heat-treated and are the best way of bedding in new green discs. However this assumes that all used parts are mechanically sound and in
condition. Badly worn or scored brake discs should notbe used to bed in new pads, and pads that have worn to suit the contours of scored or warped discs cannot be used to bed green discs. Unless stated specifically by the supplier, never "stand" on the brakes after fitted new pads or discs. Overheating brakes in the early stages of the bedding process will overcook. Pad and disc material and result in reduced longevity. Sometimes badly worn or damaged brakes will necessitate discs and pads being fitted at the same time. Even more effort should be put into the bedding in process. The longer the time, and more frequent the cycle of heating and cooling before the big "test",the better most pads and discs will perform. This in one case where
