AE92 Brake upgrade

[GZE016]

Hi,

Is there a reasonably easy front brake upgrade from Super Strut to a 4 spot with bigger disc for AE92?

Thanks but i already have Super Strut upgrade which i manage to overheat on the track so i'm looking for a 4 spot option.

How did you cook them? what pads are you running? what brakefluid etc? what rear brakes do you have?

[FMS01]

What are you overheating, the disc (and warping them) of just boiling the fluid? Have you tried a better quality pad and or fluid? Have you tried running brake ducts from the front of your car? Have you tried lightening your car (take out pass seat, rear seat, spare etc. 50kgs)? Do your pads "drag" on the disc because this would bring the disc temp way up before you actually press the pedal. Have you thought about the way you are using your brakes? perhaps you are being too gentle and braking for far too long a distance and therefor bringing the temp up too high?

What sort of events (how many laps) are you doing and on what track?

I run my AE92 at QR (admittedly not that a demanding circuit on brakes) at trackdays and after 5 hot laps the brakes are still fine, and mine are still poxy std CS brakes (solid front rotors and rear drums). End of the back straight I'm reaching 175 before jumping on the anchors and 165/170 on the front straight though I only need to knock it back to 120 for turn 1.

Cheers,
Julian

I too find it interesting that you are overheating superstrut brakes - they are quite large for a little corolla!!

Finney on these forums runs the series 2 SX brakes on his AE92 20V Seca - and has done several track days at Wakefield. To my knowledge he has had very good performance from these brakes, due to using high quality brake fluid and top notch brake pads.

PS - bendix metal kings DO NOT equal good pads

I'm running superstuts front and sx disc rear on my ae82 gze, using ebc greenstuff front and rear along with ebc racing fluid and they are impossible to over head, held up at wakefeild great, lap after lap, i'm talking 20 plus laps

I used to run Superstruts front and SX rear on my AE92 GZE with DS2500s front and rear and EBC fluid and never saw a spot of fade even at Mallala which is VERY hard on brakes.

[GZE016]

Using EBC Red with fresh fluid and about a 1.5 inch cooling duct and still have drums on the rear.

They've held up at Winton and Calder but i lost confidence in them over the weekend at Sandown. They'll pull up both 180km stops but fade 3rd and 4th lap at turn 11 so i figure they don't get enough of a cool down, then ok again at the end of main straight.

I'm due for a set of pads and discs so hoping there was an alternative.

there u have it

[takai]

When your rears are probably doing jack squat (due to the bias) then it is little wonder.

[GZE016]

So a set of rear discs and bias valve should solve it.

Thanks for you help.

[The Witzl]

Yeah i'd start with upgrading to rear discs and a new bias valve.
Much cheaper than upgrading your fronts only to have the same problem again

Go the AE101 Rears. Per that link above.
