Special Notice 06-2013 discussion thread

I had no acknowledgement to click I know that. Don't think it will change many results to be honest

Am I reading it right, that if there is a lock up on both fronts then there will never be a fail on imbalance?

Dunno about watering down... drowning perhaps...




Incredible don't you think (and not just fronts btw)? This is what I was alluding to a couple of weeks back. I couldn't say too much at the time but this really makes a mockery of the brake test. If they lock then they must be ok - right?

The SN has been "dumbed down" from the original draft some of us saw - lucky because I had a fair few comments there as well!

So then - brake performance will only fail if one isn't working at all. That's what it all boils down to. Yet another occasion where road safety has taken a back seat to politics.

when does this start,at bottom of page 1 of special notice it says

Until you receive a further special notice telling you the date of the change, carry on using SN 3-2013.

i take it we will get another special notice to tell us the changes have started

And it STILL doesn't address the fact that my rollers will not work the new system

It's still a right old mess that wont ever be sorted out while the regulations on brake imbalance (from Europe) are interpreted so literally. By this I mean that brake imbalance has to be calculated at the maximum braking effort - why can't VOSA just say that just below lock-up will do and get your imbalance readings from that. Of course that would mean that the brake performance test would have to go back to what it used to be with the added measurement for rear imbalance and that would require a U-Turn from the DfT.

I'm going to be delving into the brakes performance RfR's and failing on imbalance across an axle (it's actually still there if you look hard) if the figures are over 30%, even if the lockout figures wont fail them automatically, or now even totally ignore them due to premature tyre slip. I'm totally fed up of hearing all this crap about the computer is the only thing that can pass or fail the brakes - the computer wont help me assess a track rod end or ball joint. That's what I'm supposed to be there for.

If that goes down wrong with the powers that be, then let the damn computer do the whole test from start to finish if it's that good.

I pity the poor roller brake tester companies too - I bet they don't know if they're coming or going either with these changes (if not U-Turns then maybe 3 point turns?) every few months.

Yep
