My VW Golf VR6 passed its wof today, but i'm wondering how they come up with the brake service score, ie, it says 75%, recently the rotors, pads, fluid have been changed, so how do I get to 100%! then again, how do they know its 75% anyway!

Drive down the road, its the local garage, no brake rollers

75% is still a good average score, depending on how recently your rotors and pads were done that may have been a factor in why it hasn't scored higher, some pads can take quite a while to bed in completely.

100% is hit a brick wall.

the inspecter will try and get the best result without locking the wheels, results can depend on weather and road surface, 75% is an average performance for that vehicle.would expect 85% but again lots of variables! it passed thats what counts!

WOF inspection providers are expected to have a brake tester.I have a Tapley meter and there are some good digital decelerometers available now.They have to have there calibration checked yearly.

My HJ always measured around 90%, the wifes 4wheel disc VN only managed 78-83%, until the discs were machined and new pads fitted, then went up to 85%. All measured with the 'guage in a box' on the floor.

The Tapley gives a peak reading,the modern electronic brake testers give an average,so always read lower than the Tapley.The Tapley always reads 80% and above with good brakes,with an electronic meter 80% is very good.

All good, have clocked up 875km return trip to Nelson since this post, brakes are fine, also got 8.7L/100k average, not bad for a gas guzzling auto 2.8 v6 really for those old school peoples, thats 32.47mpg (UK)

at the end of the day( & maybe your life) its when you have to make an emergency stop that counts. If you're not sure go out on a quiet road & try some at various speeds - if not happy get the brake system checked out by someone that knows what they are doing.
