After replacing one rear brake caliper and servicing the other myself to sort out juddering brakes I still wasn't sure the brakes were ok so I got Lexus Reading to check them. I'd had enough of faffing around with the brakes. If anything else needed doing then Lexus could do it.
They checked the brakes and said they were ok so now I have peace of mind. There was no charge.
They collected and returned the car from my house, appear to have washed and hoovered it, left an FT in the car and replaced the mats under a safety recall.
