ive also had a quick chat with 3rd gen steve like @Merlin suggested and he said nothing to worry about
Cheers for that wurly and you will be glad to know what you said above is exactly what my MOT tester saidwurlycorner wrote:It's just a natural difference you'll always get from one side to another.
All sorts of things come into play...
Different length pipe runs, different diameter bore across sides (so different amount of fluid on each side, different amounts of resistance to the fluid flowing etc.) different behaviour of the flexi pipes from one side to the other (one might expand more than the other, also affecting the fluid pressure into the caliper) different efficiency of each caliper to the other, different resistance to the pad moving in the carrier, difference in the actual coefficient of friction between the disc and the pads on one side to the other etc. etc.
It will never be a perfectly balanced system.
And that's before you get into the tolerances in transferring the force into the roller and then tolerances in the machine measuring from one side to the other.

yep i do feel it pull a little bit to one side under heavy braking but then again the 30cm dia steering wheel i have is so light that i do get a load of feedback from the road surfaceMerlin wrote:Do you feel the car pull to one side while braking?
Just to show off my 5th gen had less than 3% imbalance on the brakes when Steve MOT'd my car earlier this year
I do still have a noticeable wobble under braking so im going to change over the front discs and test it out.
but like you both say - a proper alignment and tracking is worth thinking about as well.
