Front Brakes

PukkaSilvia · #1 21-01-2007, 16:47

groove your front discs or buy grooved ones and mintex or porterfield pads and then bleed the brakes right though with some decent brake fluid, and get some nice sticky rubber on those wheels and they will be the bollocks. I can lock mine in the dry at 100 ish with toyo tyres. I find my brakes to be prefectly adaquate for a 'fast road setup'

there are other options, use the forum search option

Definitely want to go for 4 pots. Bigger discs would be good too...

Are S14 and Skyline calipers the same?

Locking brqkes up at 100mph is achievable with any brakes. What you want is a set of brakes that can slow you down from 100 in control without losing efficiency ie brake fade.

Try braking from 100mph down to 30, then try it again and you will notice on the 2nd or 3rd attempt they'll fade.

Even if you have really good pads the 22mm discs will heat up real fast, and brake fade is inevitable.

The 4pots will help with the heat issues but at the end of the day the disc will be the first to cop out.

Oh and the skyline discs won't fit.

Thanks for that Martin.

So what options do I have as far as upgrading the discs?

I'm now thinking S14a calipers. So need to work out the disc side of it now.

Skyline calipers are for bigger discs, so the offset will be wrong. These discs will work nicely with them though:

That is the only true upgrade.

S14/Z32 calipers are designed for 280mm discs so bolt on with no issues. You dont actually need spacers for the thinner discs either.

Other than that, you could go for custom bells/discs that are available for the S13 but the offset of the bell might be wrong, so some measurements of the disc offset will need to be made. You never know, they may be the same.

Ok so if I go for a direct replacement of calipers with the S14 ones, which discs would you recommend?

Are standard S12 discs 280mm?

Who sells uprated 280mm discs?

S12 discs are 274mm IIRC.

You cant really upgrade to anything which fits the S12 hub. The only way is to use say the Apex 310mm S13 kit and hope the offset is correct

Martin you seem to take any oportunity to pick at whatever i say, i should not have to cover every angle of a statment i make just to stop you from picking at it like a magpie in a cornfield.

I never had that much bite on my standard discs and pads compared to how they are now It is a seriously vast improvment on the standard setup and i was reccommending it as it is a decent,easier and cheaper option.I never suffer brake fade from 'fast road' type driving.I only got bad brake fade at Rockinham after doing 120 down to 20 over and over again after about 15 minutes because of some daft chicanes they put up on the oval track.

I didnt find s14 front calipers on std s12 discs to any better whatsover than the setup i use Richard, If you are going to go for 4 pots you definatly need different discs

RichardK · #9 22-01-2007, 19:13

Yep going for the S13 setup by looks of it. Got some S14a calipers. Just got to work out what else I need...

i've noticed a difference with the 4 pots,but only since they have been installed on my mk2, probely because the mk1 had a leek and was sucking air in.
