I’m no great expert on brakes (can you tell?) But - I can see the potential benefit of holes in the discs aiding cooling. Beyond that, and unless you’re into super-speeds and heavy, prolonged braking, I don’t see the benefit from grooved discs???

I think removal and cleaning of injectors would be a reasonable (and cost effective) stage one to try and address the problem, even if it requires buying a cheap sonic cleaner. If that didn’t work, I’d go to stage two and buy a known ‘good’...

Ok chaps, update on @ChuggyFreelander ’s car… Main issues for MOT are excessive smoking and handbrake. My advice was to sort the smoking first, if dealt with, then replace the rear brakes. Seems to be an injector issue going on as the balancing...

@ChuggyFreelander Off-topic, but as promised; PB blaster is my first go-to for releasing rusty nuts and bolts. Soaking time is your friend here. Owatrol Polytrol is brilliant for restoring your black trims on the car.
