Hoppers Stoppers brake upgrade vs Pug/Lux/Corona brake upgrade

[twentyEight]

but you are forgeting the reasons as to why the calipers are getting too hot.
1 incorrect brake pads for the job (ie coefficient of braking)
2 with bigger brakes you dont need to be on the brakes for as long therefore reducing heat buildup in the rotor/pad combo.

True dat...

Tom86,

Is your hoppers stoppers kit this one? I'd be interested in knowing how hard it was to fit (assuming you did the install)

Cheers

Most people do not try to understand why brake upgrades are done. It is really not much to do with matching engine power to brake performance.
The biggest engineering factor for a change of brakes is an increase in vehicle mass.

I disagree, i think its both.
You have a more powerful engine = more energy available to get the car moving = more braking power needed to stop it.

That may not apply to the street too much, but it definatley does on the track.

i agree with MWP,

more power = reach a higher velocity earlier = less time for brakes to cool from last braking event.

upgrading to something ventilated is a wise idea

If you read my post closly I do agree with the need to upgrade for better brake performance if you are not only on the street. I notice both MWP and brett have or had cars with increased mass.

On the street you really only need the car to stop well in emergencies. If anyone runs out of brakes on the street then more fool them.

Higher power on the street does not mean faster speeds, as road rules still apply guys

Rodger, Brett's RA40 didnt increase in mass by farkall.

I would like to agree that the Hoppers kit is well overkill for street and occasional track use. Another upgrade that has come to my attention lately is the Commo/RX7 combo, which uses VL or VLTurbo (270mm and 290mm respectively) rotors and Series 5 or 6 RX7 callipers. All you need is custom lines made (probably $100 if you take the car in) and calliper mounting brackets (find a machinist that likes beer). This could well turn out to be a great value for money kit, and the VL discs have integral hubs, so buy them un-drilled, and take them to a machinist to have the stud pattern of your choice drilled in. For a TA22 with its extreme light weight, the 270mm discs should be heaps, and the Mazda callipers are quite efficient (designed to stop a heavier car from higher speeds).

Hope this helps.

C'mon rodger! You can still overload old celica brakes on the road while remaining under the speed limit! :-) Hell, I've had the daihatsu shitbox's brand-new brakes on fire multiple times on public roads without breaking the speedlimit ... just add hills!

I cooked the RT133 twin piston brakes with Bendix advance pads on my RA40... ad a combination of hills and centreline brake cooker style mags... stank for quite a while after, and squeeled for months too.
