hey guys and girls,
i want to make a trip to the ring in my nova, but dont want to user my standard small brakes as they wil crumbe at the first corner.
so want to fit some 256mm to cope. but i want to keep my 3 spokes.
can i have some advice on shaving the brake calipers so they fit under the alloy.
also what about using a 5mm spacer to get the clearance. would this be safe thrashing around the nurburgring.
or do you think i should get some cheap and cheerful steelies which will fit them??
what size spacer you need would depend on how much is left on the pads lol
i ran without a spacer but had to grind some off the caliper and use worn pads
Fit some 5.5j 14" Steels
yeh adam thats what i think i am gonna do, dont fancy shaving a big brake, when im "thrashing" around the nurburgring
and i think i have just bought some sr steels of aw06 for 20 quid. billy bargin
I managed to fit 256x20mm (TD) brakes under my 3 spokes with a little shaving of the caliper and did 10-15k on them with no issues, I used new discs and pads when I fitted them. If you're planning a ring trip though I'd fit the brakes and some 15" wheels at least a thousand miles before to wear them in. Suitable track tyres should be cheaper in 15" aswell.
welsh dan makes a good point,the td brakes are more than adequit with the right pad/disk choice...
Oh dear god people, DO NOT GRIND DOWN BRAKE CALIPERS :cry::cry::cry:
As with most things, do it right and it's not a problem. I guess you have visions of people cutting the spring lugs right off etc?Quote:

I think he has more visions that ATE designed them with the amount of material they have for a reason. Another thing that makes me chuckle is the 'use fiat coupe discs, you have to change the pads before they are half worn'. Then you might as well buy the vauxhall discs and use the pads till they run out! False economy.
+rep for having common sense, seems its in short supply these days :thumb:Quote:

They can't get to a con-rod though ;) Brake calipers are nice and accessible behind rimz innit.
People need to realise that even brake calipers have a finite strength. They are designed to carry out a purpose for a set length of time with set operating conditions. By the time most people get their hands on their super duper ATE brake upgrade, that design life is probably near its end. To then remove material from the highest stressed area of the caliper is STUPID.
you see you say that but vauxhall made novas with funk more material than any of us have got, especially you oli. think of shaving your calipers as weight saving lolQuote:

I bought mine new to avoid the second hand gamble.
Please don't take this the wrong way as I'm mearly illustrating a point here:Quote:

My point was that if you do something right and understand what the consequences could be then you will be fine. I appreciate common sense is long dead in this country but meh.
I get your point about the weakness of the caliper after, BUT i have done the large trim on my calipers for my 3 spokes, i know it makes a weakness right on the corner but that is where all the stregh is there is so much metal there and theres so little compared acutaly inline with the disc, i havnt even touched that bit.
Never heard that one :wtf:Quote:

The highest stressed area of a pin-sliding caliper is the fist portion, and ultimately the area where the fist curves from the horizontal disc spanning portion to the vertical for the pad backing.
One thing that is been forgotten here is that this car is only a 1200,would Gte brakes suffice? Its hardly going to be stopping from high speeds is it
Do you mean this type of caliper (Astra GSi ATE's, not mine btw)?Quote:

Or the older type that actually did have pins holding the pads?
those are pin sliding callipers so are the older gte ones, just they also had pins that hold the pads inQuote:

Anywhere in this area is a big no-no. Not that I'd advise removing it from anywhere else at all.

Coolio, cheers for that - I wasn't sure what the proper name was :thumb:Quote:

Yes unfortunetly my cross member was weak and caused other problems. Big difference in my eyes is, a mate and me over looking something budget a few hundred, a manufacturer like ATE who would have developed and researched how much material is needed. Sorry brakes are just a gripe of mine, I go out to alot of joe publics who 'maintain' there cars by themselves. Few miles later they call us out to tow them home.Quote:

and i have just got some 5.5j sr steelies from aw06 (thanks), so if i do decided to get the big 2.0 brakes then these will run them fine. with out any shaving
thanks for the opinions.
Unsure if they fit but Corsa Sport's have bigger than standard nova brakes. More than likely nova gte stuff thouygh.
Martin catch me on msn again later :thumb:
I'm not surprised, must be quite soul destroying!Quote:

Well I've been told that the spring clip is needed, they then called me out to ask why they have to pump the pedal to stop... lmao
on the mk3 astra they did a 236mm ate caliper that fitted with the nova gte sized vented disc. it stops quite well & you don't have the delco caliper problems with the sliders locking up & the pads jamming.
The spring clip is VERY needed. Its amazing how much difference that makes lol
And ive got very worn pads in my turbo calipers atm with fiat coupe discs. There fine, not spaced out or anything.
Yeah, you wouldn't think it would make that much difference! I would imagine if left the caliper would shear the mounting bolts.Quote:

I've got corsa brakes with £8 budget pads, and they have taken a lot of beating, think I've only had brake fade once!! So good pads would be great!
cheers for the ideas people i now have a wide selection of brakes available to me lol :)
tigras had 256 by 20mm discs, whereas most 256's are 24mm. I've heard that they fit fine under the 5j 3 spokes.
that might be a place to look, big brakes small discs, will the fittings be the same?
yep, same as corsa sport 1.6 ones. fit under 3 spokes. just.
