Thank you so much for the info, I'm basically about to take the guy to court for a partial refund. I had a caliper seize on the front near side, so I decided to replace all the discs, front two calipers and all the pads. The guy started work on the car and called me out to say the rear calipers were also seized, I found this hard to believe as I'd driven back from Cornwall to Norwich the day before yes the front near side was scoring the disc for the last 100 miles but was fine to drive with care.
He showed me he couldn't push the piston back in on the rear calipers with big grips BUT I'm assuming this would be because the brake system ' locked ' so to speak.
He also showed me the rear brake shoes for the foot brake and said they were very low on pad material BUT my local Lexus Specialist tell me these shoes are almost never replaced as they only open and close when the vehicle is stationery so they simply don't actually wear out and need replacing, he clearly didn't know these shoes only have a small depth of material and mine were actually hardly worn at all after talking with Lexus.
As for the rear near side brake hose he could get no fluid out when he tried bleed it so again I'm assuming this is because you can't just bleed the brakes like you would on a standard car brake system ?
I wrote to him with registered post with a complaint and asked for a partial refund and he never responded, I wrote again and hand delivered the same letter and it was returned by the post office because he refused to sign for it !
When he had put the car back together I had some front brakes and managed limp it to the Lexus specialist who put it on their machine, reset everything including the ' Christmas tree like dash board of lights ' that had come on and adjusted the rear foot brake as it wasn't working correctly.
After all this and the guy charging me ten hours labour I think I have a pretty good case to take to court ! I just wanted confirmation that this car needs to be on a specific machine in the workshop and you simply can't do this job on axle stands on the drive.
Thanks guys
