A vented disk won't give you any more stopping power, it will just dissipate more heat allowing you to abuse the brakes a little more before they overheat.

The vented rears are designed to work with the same front end braking setup so the pad & piston area will still be correct, and probably the same as the non-vented setup so I would be very surprised if retro- fitting them upset the brake balance.

thanks for replies, i'm only interested in doing it because i wonder at times if i'm going to cook the brakes (its an auto) an at times i do give it alot of abuse going flying towards corners and maximising the right foot on the old brake pedal (well it must be so big for a reason-to give it a good stomp )

i'm on about putting the 2.0 front discs on (286's which i think the rears are anyway on the 2.6) ... if there's an issue with handbrake operating- or not in this case then i'd have to buy some 2.6 discs

and anyway i understand the brake bias principles
hence why i wasnt going to put a bigger diametre on the back than on the front

Not sure its worth the effort - its the fronts that need beefing up, unless you are track racing.

The fronts do seem to complain first if driving is spirited. As it was on my way to work one day this week.   Decided my new disks had had enough bedding-in and it was time for a work-out. Got a few dirty looks when I rolled into a village after a bit of a session on the backroads to find the bin men doing their round and blocking the road. .. and I'm sitting there with both front wheels smoking like Dot Cotton.

I've got brake problems on the tractor - when I went to Belgium last week I was running late, and lost the brakes going through Milton Keynes.  First time I've ever had serious brake issues on Omega  

Anyway, I've rebled, and filed the front pads a bit, but can't get the bite back - do I need to replace the pads?

Not entirely sure I haven't warped them  , which is a shame as they were only renewed in Feb

what sort of symptoms are you getting matey, spondgey would you say or you just seem to plonk your foot on the stop pedal and doesnt have the same response as before?

Sponginess went after I bled them (pedal went to floor on Thurs).  Issue now is lack of bite on the pads when stamped on, bit like first mile or 2 after brand new pads

[ngrainqey]

might have glazed them, can be a right barstuard to get rid off in my experience.
tbh unless somebody knows how to get rid of it then new pads matey

especially the note right at the end, last sentence ?

might be worth a try ??

all that happens under ferocious braking on the track(both cars) was that the abs cut in on the rears a couple of times

The fact that the ABS had activated on the rear confirms there is a brake imbalance, all be it a very slight one.  

ABS is designed to cut in when a wheel has or is about to lock up. Without ABS you'd have soon binned that idea...or up-rated the front accordingly. If they're good now, they would probably be phenomenal if you did that.

Stickier tyres on the rear may sort out the loss of traction activating the ABS, but you would then run into other problems like a much higher risk of loosing the front end sooner than the rear when cornering on the limit.
As you probably know, loosing the rear is not too much of an issue, (in fact with the motorsport of "Drifting" it's the name of the game.)  and probably happens several times in every track session or race. If the front goes, then it usually ends up in the kitty litter.
 

nearly right!!! the rear abs only cut in cos the rear shocks are blown!!!! there is no actual brake imbalance with this set up bud, its what is used on the 3.2 and i agree its really only on the track you are going to use them to full potential, but it is a very good safe modification and as someone else has said apart form the better swept area giving more brake power the only other thing that is improved is the actual heat dissaption form the vented rears
its a good safe modification to do in my opinion

simple answer is you burnt the resin in the pads they will never be right now!!! will always feel bad rectification? put new pads in!!!!

[pete.h]

You probably know this already but on  a lot of vauxhalls , it knackers the abs unit if you don't crack the bleed nipples when you push the pistons back.

Something to do with fluid being forced back through the unit I think.

Anyway the end result is the pedal creeps and you can't do an emergency stop , although under normal braking it's not too bad.
