(the brushes are the first and CHEAPEST way to progress)This is a LOT CHEAPER than having to BUY a new/exchange MOTOR ,if a service man comes out to you, he will tell you your motor is duff charges you for a new one that he just happens to have on the van, fits the new one and (TAKES yours AWAY re brushes your motor) and keeps it for the next sucker that thinks there motor has gone the cycle is then REPEATED etc etc
