I booked my car in with a fault of juddering brakes and a grinding sound when turning right. Halfords St Albans replaced the discs and pads £400. 5 weeks later same problem re occurred. Halfords replace the discs and pads three times over 4 Months, never diagnosing the actual problem, despite repeated prompts from me to investigate. I booked in to an independent garage who diagnosed the fault in 30 minutes. A damaged wheel bearing.He said he cannot believe that a mechanic could put the car on a ramp and not notice that the front wheel was so loose that it wobbled around. So I drove around in a car with a major safety fault for 5 Months and 5,000 miles due to Halfords incompetence. I will never use again.
