Brakes Imbalanced across an Axle

I owe a 2000 Renault Megane 1.6 16v Sport

My car has failed it's MOT with a few issues.

One which i don't understand is:-

RBT Brake Imbalance 20% and 42%.

What does this mean, and how can it be sorted.

I was advised that the drums could do with a good scrub, and the shoes replaced.

Would like some advice please.

Sounds like they're saying one side is working better than the other.
Follow their advice and strip the brakes.
Free off, clean or replace as necessary.

Re: Brakes Imbalanced across an Axle

Brakes don't wear evenly so there will always be some degree of imbalance between the two. Possibly one shoe has worn a lot more than the other side, you could have a sticky handbrake mechanism holding one shoe closer to the drum and wearing more, a brake cylinder piston could be corroded or sticky, a return spring could be weak, there's an excess of dirt & dust inside the drum, or a drum could be worn out of 'true'.
Hope this helps.
