MG Midget and Sprite Technical - brake test results from MOT

Evening all.

Some (daniel s?) may be interested in my brake numbers

Front left 165kgf front right 182kgf
430kg over front axle, 11℅ imbalance and 81℅ efficiency

Rear left 169kgf, rear right 205kgf
464kg over rear axle, 81℅ efficiency again, imbalance not required

Handbrake pulled rear left 116kgf rear right 115kgf
26℅ efficiency

Total weight is in at 894kg, seems a bit much but the tester is a big chap.

green stuff pads with standard discs and calipers with braided hoses, new shoes on back with 100 miles or so on them

Interesting or what... :-)

Just MOT'd mine and didn't note the numbers but the tester did comment about the 28% handbrake efficiency - "it locks the rear wheels OK". As the minimum is 25% it passed OK.
