been to stappletons,the nice young man,about 17-18 said cor I have always wanted to drive one of these!thought he was going to tare off down the road!any way said he couldn't find any leaks,but possably oil from my leaky hub seal getting on the brake shoes causing it to slip...how likely? do we think this is possible? obviously will get Tim to have a look and will bleed the brakes again!what do you think any one?
