Uprating Brakes?

[System~G]

The time has come to replace the brakes on all four corners of the rolla. This will hopefully only involve the discs and pads. But I wouldn't be surprised if the calipers will need replacing too

I am contemplating uprating the brakes with some EBC discs and pads. I have 15" Fox racing alloys currently fitted. Is it posible to increase the diameter of the front discs using the existing stock calipers? If so What's the largest one can go?

What are the better type of disc to go for:

* Drilled?

* Grooved

* Drilled and Grooved?

* Or Standard Vented?

I have heard many conflicting reports on drilled and grooved discs so just basically wanting your ideas with regards to the Corollas braking performance.

Is there another manufacturer recommended?

I am on a relatively strict budget so can't go the whole hog :( But pricing up on EBC's website for stock equivalent doesn't seem too bad...

That makes two of us System G

Im looking to sort my front discs, but Ive had reports that cross drilled etc discs are not worth the hassle?

Does anyone have a cheap but effective suggestion?

[corollasr]

i think its trc-tuning.com who sell Brembo max discs for the rolla. they weren't too expensive either

Makes three of us cos the old rolla requires new calipers and discs

Just done the front on my rolla

1 new caliper and disks both sides, (but overhauled the other caliper) I just went for direct replacement parts ie blue print disks and a stndrd toyota caliper remake!! costs about £140 all in! and only took 2 hours'ish

Not too bad mate

I paid £90 for blue-print discs and pads for the front of my MR2 and replaced them in about 45 minutes... But I didn't have to mess about with calipers, re-plenishing the brake fluid and bleeding the system.

[System~G]

By the way Dave, where did you get the replacement parts?

[dave5282]

A local motor factors supplier, saved a few quid (about £20), as I have a contact of sorts. bleeding the system was'nt much fun though!

But if you look in Gold, I think you will be able to save a bit!

I think I may save a bit more by going somewhere else (not part of gold discount scheme :( ) BUT, I am going to try get them onto Gold discount as well B) :D

This aside, I am still trying to find out what the largest size discs I can fit on the fronts using 15" alloys and stock calipers... Anyone?

[System~G]

In the last week I have managed to get EBC Direct and another budget brake supplier into the gold discount scheme

I still need to know what the largest diameter of discs can be used on the front of an AE92 with 15" alloys. Anyone?

I think the only way to get bigger discs on using the standard capipers is to physically move the caliper away from the hub using a bracket of some sort. I've been looking for the last 12 months to find a company that makes them but I'm still looking. The only way for me seems to be to go for a complete custom job and that will be very expensive. The alternative is to go for standard size grooved discs with uprated pads (although the Toyota ones are pretty good - mine have lasted over 5 years and still have some left) and get some braided brake lines with a change of brake fluid (should have been changed a while ago) as both deteriorate with age and use. That would leave the front/rear balance the same but give a much better heat dissipation and a better feel to the pedal.

[System~G]

Cheers for the info! It's exactly what this site should be for!

I thought it might be the case - using stock parts with uprated ones... I can't afford the expense of custom jobs. Least if you stick with stock sizes but uprate quality you know the braking will be a little better B)

The brake fluid was all new a little over a month ago as I had the entire brake line system replaced - but didn't get the hoses done (due to budget). The hoses are still fine but there are signs of perishing begining - so they will need to be done too which will mean another refill of fluid

[ae111sr]

The trouble with standard hoses is that they tend to bulge when you put your foot on the brake pedal and pressurize the fluid. With braided hoses the braid prevents that happening so much and the pressure gets applied to the pistons in the calipers instead - better feel and less fade. Upgrading the fluid is also worth doing it has a higher boiling point.

Can I just say (dont mean to be off-topic) but thnks guys, I just sat and read through this, and learnt something, Cheers

If your good with maths and a welder then the brackets themselves are easy enough to make (Not that I could do it!) but I know a few people who have managed it on a different car forum (Not Toyota or Corolla).

I've just put Black Diamond drilled and grooved discs on the front of mine with some EBC Greenstuff pads. The brakes feel a lot better than the old worn out parts but I've never thought of the brakes being that good to be honest. The rear pads need replacing now too! Never ending!

I also had to have one of the front calipers overhauled as it was sticking, new seals/gaskets etc. One of the rear calipers was binding too but I think it was a sticking hand brake cable.
