Some of you might remember the green SR I bought and broke which was mckenzies then Shaun's. Before I bought it Shaun was trying to figure out why there was really bad vibrations when braking and changed a lot of things with no luck.
When I bought the car it had extended studs all round which I took and put on my car at the back and behold! Bad vibrations. I noticed this:
The 'neck' of the extended stud sticks out about 1mm give or take. Which meant the disc wasn't sitting on the hub but on the neck if the stud :O.
Grind them down and hey presto!
So if anyone has/getting extended stud look out for this! It can be dangerous!!!
