UK MOT's

Hi Don, just two wheels at a time, front or rear. Imbalance is left/right front only as the back seems to be fine. There is no ABS on the back.
I need to get to the bottom of this in case it is a problem that leads to a greater failure.

Front to back imbalance isn't dangerous but left to right can be.

Hang in there. I am typing up a reply and will post it in a few minutes.

Darren:
There should be a front to back imbalance, but not left to right.
The machine says 60% imbalance which should be not only hard to control on the road but downright dangerous.
Thing is it doesn't show up on the road at all. brakes really nicely. Even the tester was surprised when he took it out for a spin, he was expecting exactly what the machine told him. The spin which I insisted on was the only thing that persuaded him to let the car pass the test.
Where do I go from here? What am I supposed to believe?
I put two new front tires on for the MOT, both were well worn, but evenly........should that be any indication...I doubt it.

Darren.
Just talked to my son about your situation.
You may have a flex line that is starting to come apart from the inside. When you step on the brake pedal a piece of rubber that is deteriorating flexes off the inside wall and tries to block off the hose causing a pressure build up.
Another possibility is with disc brakes sometimes as the calipers get old they can stick and require extra pressure to expand them.
I am not sure what parts you replaced but I seem to remember that you had to do some work on the front end to get it ready for your MOT check.
I'll keep thinking on this end and we will get it figured out yet.
Cheers :beer:
