we never look after are own cars us Mechanics, as i went to bagshot then to walton on thames. getting to a car park in walton found a lot of smoke coming from my rear wheel.removed the wheel and the very hot drum let it cool down then rejust the brakes. so i hope this never happens again but i have got to replace the wheel cyl at least.i think the shoes got caught on the rust inside on the back plate. well i think it just a case of keeping a eye on it for now.
