Daft question, but taking the car to the garage on fri afternoon to check the brakes on the rollers pre-sva.

What % do I need as a front to rear comparison?

thought there was a load of calcs in the manual on C of G etc and the brake effort had to satisfy that lot?

If its just front before rear then no probs, I know it does that...............

yep - load of calcs - designed to ensure front before rear on all surfaces (ice to dry tarmac). If your fronts lock first on dry tarmac & you have a bias bar (or nothing at all) you'll get through

so my harness gets it first official outting - be careful with it, don't do anything silly, i don't want any stretching or blood on it ok!



(remember, i've been your passenger!)

do a search, i'm sure this has been covered before.

My SVA tester told me that my car was overbraked on the rear calipers (std Sierra) and needed to tweak the balance bar - I still passed though.

I set my bias almost fully front. On the rollers it passed no worries (helps that the MOT guy races monoposto, so is sympathetic to non-standadr stuff) The rollers were knackered on the second year so they did the road test using the accellerometer - for that they needed the vehicle weight (which I knew) so they calculated it as OK too. I'd let them know when you turn up - hopefully you won't have a station where they keep you away from the tester. Best bit was the emissions - mine were taken from a Laguna! Happened to be the nearest car to the emissions checker.

dude when they checked my car he was very serious about all the measurements and readings

go with bog standard pads and make sure your fronts lock up first on your private test road your 90% there

Ok, cool.

Thanks all.

My roll pin on the bias bar may prove "compliant" enough to allow the neccesary adjustment!

How?

I didn't even have my bias bar locked for my test! The tester was happy with it though.

I have the aforementioned "roll-pin", and I also have an alloy cover/footrest, which I want to fit over the pedal box, but I'm not sure whether if I fit it he will fail it through suspicion!!!!
