WOF Brake Test

vtecnet, Apr 22, 7:17am
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!

did they put it on rollers with the test gauges! or just drive it down the road!

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

the wofinspectors use the guessometer or the tapley

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!

Pass is a pass as they say

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.
