brakes dont lock up because they are bigger its how hard you press them that counts

256mm (14’s) For Less than 130bhp
284/288mm + (15’s) for 131 – 199bhp
310mm + (16’s) for 200bhp+
330mm + (17’s) over kill
A good rule of thumb is get brakes that just fit under your wheals.
and stick with drums on the back if a corsa needed disks on the back vauxhall would have put them on
Also get good disks and pads don’t get cheap stuff

the back brakes do about 10% of the braking, there really is no need for discs on the back, the corsa just isnt heavy enough

I have got 256mm on my 1.4 runabout and they fade like you would not believe, so putting them on a car that can go 120mph+ is not a good idea.
And on a 2nd note I don’t believe the 288mm brakes are good enough for a LET.
Brakes suspension and tyres are not to be done on the cheap if you want to protect your investment.
Modifying your car to go fast is not cheap so don’t do it cheap, it’s not worth it
You go and look at a fast car (i.e. 911) that will do lets say 170mph (that’s what a 300bhp corsa will do) and go look at the brakes. Bet there bigger than most people’s wheals, is that over kill or do they know something that 80% of people don’t know?
People just think “I can put a XE/LET in for about £1000 - £1500” Wrong!
You then need to spend that again to do it right.
A XE/LET that is well set up will be faster and be more fun and safer than one that’s been done on the cheap.
And when you’re at a shoe ones that have been done on the cheep stick out like a big ZIT!!!

yeah, definitely. brakes are one of the best upgrades i ever bought, nothing else made the car feel safer as much as they did.
i only managed to get them to fade once, after repeated abuse between loads of roundabouts in MK

well i got 256mm already and they arent to bad, work much better on this then they did on the GSI as the ABS always messed things up
on my mk3 astra i have 256mm but after i did the rear disc conversion that made a massive difference the feel in the pedal was so much better
i wouldnt go a for a cheap setup, the only used part would be the calipers otherwise id be getting new disc's and pads from vauxhall

brake fade is more to do with the pads and discs being used. I agree that bigger discs will disperse heat better and reduce fade but its not all about the size of the disc, its also the size of the caliper.
I had 256 on mine with 170bhp and they were fine but I also spent money on getting good pads (mintex 1144's) and never had them fade. Now I have 310mm 4 pots and they stop very well, never even a hint of brake fade but the corsa master cylinder isnt anywhere good enough to cope with them.
to be honest, for everyday driving I prefered the 256 set up over the 4 pots.

i have 256mm rear discs, 288mm v6 front discs and the braking is 100% i wouldnt bother changing mine for 4 pots, people who say rear discs are pointless need to drive a car with them on and set up properly. mine is so much more stable under high speed braking now.
also they fit under my 15's

Man talks sense with a lot of things.
But not with regards to rear disc setup. Corsa was never meant to go quick hence why it was never considered. It does make a lot of difference.
256x24mm brakes from the GTE are sufficiant, but will fade on a track day. 256x21mm from the Corsa GSi are much worse, that few mm width makes a lot of difference. 236mm, dam, they are just scarey useless 
Im running 288mm fronts and Rear discs on a 2.0 288mm simply are no-where near good enough for a LET.

288's on mine with 17's. Had a few hairy moments involving brake fade when using them loads. Other than that they do the job.
Bit like anything, youve got to make do with what you can afford. Im sure everyone would love 890mm reyland 14 pots (can someone do a photoshop?)
