Brake balance ...or lack of it.
The F27 failed SVA on the rears locking before the fronts.
Lots of head-scratching as the smaller cylinder was to the fronts and then I thought the (fixed) balance bar was the wrong way round so reversed
that.
Rather than risk it failing again I decided to put in a set of "cooking" pads rather than the Greenstuff ones.
Replacing those at the weekend I discovered that the used discs (which had cleaned up nicely) had a rusty ridge right at the edge of the disc nearest
the hub on both sides which was about the only surface contacting the pads - no wonder there was little braking effect.
So a cautionary word - when using seconhand discs make sure the whole disc surface is clean and even before fitting - benefit of hindsight and all
that....
Cheers, Pewe

I presume this is a poll in which case I would suggest 'Brake Balance' rather than the other option which is 'lack of it'!

I agree, definitely lack of something.

Guess the moral of the story is not to use 2nd hand disks with new pads then hey. I've given up trying to reuse any disk now when i fit new pads
on any car - they are cheap enough these days to swap together - at least standard disks are anyway.
So have you fitted new disks now and tried your brakes again then?? One good reason for driving to SVA is to bed the brakes in which are always going
to take some time!! Even better to do a shakedown test in the form of a cheap trackday i recon

If its Cortina M16 calipers it has all the signs of a seized caliper piston/pad. --- check the pistons are moving by remove one pad a at a time
and pushing the pedal gently to move piston carefuly out 5mm or so and also check the pads are free to move in the caliper.

Thanks for the constructive thoughts guys.
I think it really was the rusted ridge causing the problem. the ridge had all but worn the pad edge so the main pad surface was starting to make
contact but I'll check the piston action anyway. I overhauled the calipers when I originally bought them and the bores were pretty good.
Tempted to pull a sickie on Frid. as there's a trackday at Hullavington nr. Swindon. The weather forecast looks soooo good and at least
I'll have achieved the target of having it up and running this year.
Cheers, Pewe
