Now that my cars making reasonable power its exposed some weak points in the spec that I'd like to address. The rear brakes were always questionable so I'm looking for options.

I have brembo fronts with mtec discs and carbon lorraine pads, initial bite is great, pedal feel and progression but I feel like theyre doing a LOT of the work.

Rears are standard 2 pot 290mm, standard discs/pads so I have 2 options. Decent disc/pad replacement or change to 316mm brembo calipers etc.

Question is, can you feel the difference going from stock 2 pots to brembos on the rear of a classic?

I also have a bias valve that I could install, but would prefer the braking system to work efficiently without it. I love a non-abs car, I'd just like more confidence in the brakes.

Unfortunately at the present time I dont have the budget for decent branded calipers (k-sport, AP etc) but theyre on my to do list.

I know theres some moderate to high spec Type R's on here so would be interested in the owners views on braking options.

I thought the thing to do was to remove the BIAS valve, giving a more 50/50 braking setup, as with the BIAS valve its more like 70f/30r ??

I've had AP 4 pots with both and honestly noticed no difference

Makes a difference on the heavier legacy but I will be running Brembos front and single pot rears on the SF5 thats coming I run brembos front and rear on all my other classics though lol

Rears dont matter. They are just to keep the back end stable when braking at high speeds. They dont really do any of the slowing down.

Problem is, when heavy braking you can hear the rears working really hard compared to the fronts.

Are there any guides on removing the bias valve?

Hear in what way?

Pads and discs ok? You shouldn't hear anything other than wheels locking up, etc.

All the discs/pads were new less than a year ago.

If braking from high speed, when you brake hard you get a sort of groaning from the rear brakes. The fronts will eventually lock up but I dont like to push the brakes to that point.

Its hard to describe, but you can just tell that the rears arent contributing as much as they could, hence why I wondered if I'm likely to notice a difference going to brembo rears

rears make a massive difference on a 4wd performance car - if they dont then your not driving hard enough
they dont run to the same temp as the front BUT do contribute highly to the overall STOP

at min you want a decent set of pads in the rear 2pots but a far better result will be to uprate the rear pads and calipers

Alyn them DBA discs and pf pads for the rear 2 pots balanced the car out perfectly, even with the increased power they stop the car on a dime with no locking up

The late, great Harvey Smith did the brake bias removal mod for me. Car now stops flatter and quicker.

Sorry to jump into your thread, hopefully you'll forgive me being a fellow type r owner

Are new age brembos on a type r with appropriate discs and pads all I'd need for hard track driving ?

I really, really detest brake fade so I was wondering how good they are when pushed hard for a period of time

With the greatest of respect, you're gonna need a Ouija board to get a how to guide from Harvey.

A look onto the NASIOC site brings up a few ways fo doing it
