Hello everyone, just a couple if quick questions. 1. How many miles do you consider good for cleaning the dust out of the brake drums? The service booklet of my Renault Clio says to do it every 40,000 miles but the service manual recommends every 60,000 miles. I don't know which interval to follow. And 2. Do I need to replace the axle nut every time I take it off? The service manual doesn't say anything about replacement, but the eBay kits, like the one below, come with a new nut. Thanks in advance for all your help.
