Brake Upgrade Question

[ashneel]

Hey guys

Its time for me to start looking at upgrading my braking so thought id start with the small things first and move my way up, and was wondering if I can grab some info on what to use and weather the plan I have is the right one or not.

Now I am planning on hitting the track but only for fun nothing to serious so I don’t need anything hardcore like what some of the boys here are running as I am planning on upgrading to a GTR in the next year or 2.

So at the moment under heavy breaking I get vibration so that would be the rotors that has uneven wear??? so instead of getting these machined id get them upgraded. Now does it matter if I go cross drilled or slotted rotors or get one that’s cross drilled and slotted??? Not really sure which one is better or which one would suit my needs better.

At the same time ill be upgrading my pads to bendix ultimates or if anyone could suggest anything better.

After that will be upgrading brake lines and will be fitting GTR brembos and will do a full flush of the brake fluid. Would the rotors I upgrade to be suitable for the brembos? Or will I need a different size rotor for the brembos?

also forgot to mention its for an R34 GTT

If you are upgrading to a proper car, ie a GT-R then don't waste money on such things as callipers etc on your present car.

To answer your questions:

1. A pulsing pedal is indicative of a warped rotor - weither get them machined or replaced.

2. If you are going on the track then avoid cross drilled rotors.

3. Bendix Ultimates aren't very good. But they are really dusty.

Just get the following bits:

1. New/machined rotors - preferably new if you are going to a track day.

2. A half way decent pad - I would recommend a Ferodo DS2500 but there are plenty of others that are not too dissimilar. Probably a good idea to get fronts and rears as who knows what is on the car presently.

3. Some new fluid. Probably doesn't matter so much what it is, but the key is new. If you want to get the best stuff get some Motul RBF 660 - 2 500ml containers will probably be in the $60 to 470 range.

4. Some braided lines if you really want them. Just make sure they are ADR compliant.

5. In a general sense a master cylinder stopper usually helps pedal feel.

If you are learning on the track massive brakes are not necessary. It tends to be one of the last things people learn to use properly. It is also one of the least influential elements on your lap time. So spend your money elsewhere.

hmmm thanks for that.

so what rotor would be best recommended???

as for braided lines. will i need them??? at most ill be doing 1 or 2 decas a year and maybe one or two track days but would also like a decent setup for the streets.

keep your standard calipers... i had race brakes RB74 pads in my r33 gtst and had dba 4000 series rotors and replaced the fluid with repsol competition stuff.. i didnt track it, but i would do the putty rd nearly once a month.. they did the job pulling the beast up from silly speeds coming into tight corners, never had brake fade... minimal dust and noise.. and always had a good pedal feel.

drove a mates rex down the putty to superlap on sunday and it stuggled after a few corners... the fluid would boil and lose braking feel, pedal would go to the floor.. it has semi slick tyres and they were overpowering the brakes..

Well there is best & there is cheap & there is alot of ground in between.

The RDA group buy are pretty good value if they are still around.

No you dont need braided lines. But they do give you a nicer (harder) pedal feel.

If your not into anything too serious at the track, then you will more than likely struggle to drive out of your stock braking capabilities if your car is mainly stock itself performance wise. IE Stock turbo + bolt ons..

This of course, if you have good pads and fluid. Standard rotors will also be fine.

Tires do wonders too You cant go past a decent set of tires. They improve braking a hell of a lot.

standard rotors will be fine... yes, and in overall braking performance, rotors dont actually increase braking... what they do is remove gas and heat buildup much better and constantly clean the pads.. chucking a set of rotors on and heading down the street you'll stuggle to notice an improvement, its only under long hard braking from high speeds to slow speeds when the brakes just feel like theyve stopped working.
