^correct, MOT stations don't know about it, get them to call VOSA

check you're valve isn't ceased anyway

the bulletin explains that some 172Cups were being failed as the testers were confusing the set-up with the ABS equipped cars - the Cup's got a sprung load-sensing compensator block above the rear axle. then it goes on to mention that some vehicles are just engineered with very little rear brake effort (as in this case). i've not had any bother with my tester, but you could see if that document satisfies them

it's also worth taking the car out for a blast and giving the brakes a hard time before they retest it, as the calipers can become lazy due to the lack of work

[Bizzle]

what valve? do you mean a diverter block?

[Henry]

there's a picture of it in the bulletin - the solid lines from the front of the car go into it, and the rear flexi hoses come out of it. rear beam

 

[Fred@BTM]

it has a large arm hanging off it, give it a tug and make sure its not stuck

 

[Bizzle]

ok

surely there should be some pressure going to them though. the tester said there was nothing with the braided hoses on and then virtually nothing when they changed them back to standard hoses

 

[Henry]

blokes, sorry - think i've confused the issue with some of mine. it does make sense if you read the bulletin and compare that with what there is on the car (which i've gotten wrong i think; haven't looked for a while)

 

[Fred@BTM]

check the arm isn't stuck, to pass it, cable tie it down round the axle, normally works

 

[Bizzle]

ok sweet ill do that when i get a dry day.

thanks for your help, both of ya
