No handbrake if you do that

FL V6 rear set if desperate

ok matey, i'll see how i get on and then pm if i get stuck
thanks

[ngrainqey]

I had an interesting experience..if you want more effective brakes play with the compression ratio of the engine itself..on my previous car I modified the engine increased the comp ratio with some headwork..and brakes become superb..

does increasing the comp ratio increase the vacuum so increasing the response from the brake servo?

i only had the idea because you can get the single disc upgrades, surely if the upgraded singles are so good then wouldnt they have a similar effect to the standard spec twin vented ones?

initially the mechanics and I didnt have any idea about what will happen to the brakes..But that was what happened..

I think brake servo is number #1 factor for brake distance.. and even a newer brake servo will be more effective IMHO.. :-/

spose so,
i'v got jeremy clarkson head on again though... it's like...why not put rockets on a reliant robin and make it go into space?

....why not put the twin vented discs off the front onto the back of another omega   ? lol

these "why not" s caused real troubles in my previous car (because I play with many things)  and after I was forced to sell it

lmao!
i'v already done the "why not swap the 2.0 for a 2.5"
at which point i'v got stuck because i cant get round the immobiliser so need to get the 2.5 ('94/95) ecu and everything for it to run- and yes i did get a bit angry lol!

Look in the positive side..You really learn many things and get bloody

experience that most people cant imagine

have to agree, there is that lol
anyway im off to bed so talk to you lot tomorrow night *waves*

Your existing brakes, if in good condition and working correctly, are more than powerful enough to lock your wheels (or activate the ABS in this car's case).  In other words the standard brakes are already powerful enough to stop the car as quickly as the grip available from the tyres will allow.  This is the limiting factor in your stopping distance.  Bigger brakes will not make you stop any quicker - it's a myth!  Bigger brakes will simply mean you can try and test this claim a few more times before you melt something:).  If you want to stop quicker you need more grip - get some thick sticky tyres!

You don't want the same braking power on the rear as you have on the front, especially under heavy breaking.  The weight is transfered to the front, the rear becomes lighter and as a result has less traction. This results in less braking force required to stop the rear wheels turning and they will lock up surprisingly easily.

I had an example of this in a Carlton I had several years back.
An oil hose had split and was lightly spraying out an oily mist that ended up on the front discs. As I approached a set of traffic light on an A road, the lights changed and as I was driving into low sun I didn't notice the amber, just the red. It was soon enough to stop safely but as I braked only slightly harder than I would have normally, the car slowed and then reacted as if I had yanked the handbreak up. The rear came around and I ended up at a 90 degree angle to the direction I was originaly heading.  
A certain part of my anatomy went from the size of a sixpence to the size of a manhole cover and back again several times. I had no idea what had caused this so I pulled over to the side and started going over the car. That's when I noticed the light coating of oil all over the engine bay and the inside walls of the front tyres and realised what had happened.

Correct brake balance is critical on a road car.  Yes, rally cars etc can switch the front/rear bias as required but that's totally different situation to your local high street. Omega brakes that are operating correctly are as good as you could ask for.

Take a look at most sports bikes. Twin discs on the front and one on the rear.
Also read the blurb on the back of a box of sintered brake pads. It states that sintered pads should never be used on the rear if they are not fitted to the front as this will result in brake imbalance
It's ok to use sintered all round or just on the front and standard on the rear.
Sorry, I think I'm going on a bit !!

ok guys, i have fittred 3.2 vented rear discs and calipers to a 24v diamond carlton estate and to a 24 senny track slag can report that the both of them have phenominal brakes now and the brake balance hasnt changed much at all, all that happens under ferocious braking on the track(both cars) was that the abs cut in on the rears a couple of times but the stopping distances were brilliantly shortened compared to the standard set up wouldnt do it on a four pot with the smaller front brakes but as an easy brake upgrade on the larger cars its worth doing!!
in my opinion!!!
diamond estate is used a lot for towing and it certainly helps there as well, in fact if i decide to keep my TD nad not replace it then i will probably do it to that as well,

This mod ^^^ has been approached sensibly - ie swap existing rear discs & callipers for improved rear discs & callipers.

Putting front disks & callipers onto the rear as ngrainqey proposes is gross stupidity as brake balance will be crap - to the point of being dangerous.  My advice - if you dont understand the fundementals of brake setups dont muck with them - & I give this advice with practical experience of playing with brake balances on the race track!

I'm pretty sure the fronts won't fit the rear anyway . The offset on the rears  is a lot more than the fronts because of the internal handbrake shoes.
Also the calipers are twice the size on the front so the mounting bolts are further apart.
You'd have to do a bit of serious modification to get them to fit and get a working handbrake.

I've MOT'd a lot of Peugeot / Citroens where the rear brake compensator has siezed , transferring greater effort to the rear brakes,  makes them interesting to drive , especially in the wet.

[Turk]

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.

I upgraded my last mini facelift Elite's rear brakes using 3.2 facelift vented disks and calipers.
