Hi all.

Did my normal search, yes I know how to use it properly.

Real quick and easy question which only some people will be able to answer.

With cold braking, how bad (or good) are the DS2500s in compairson to the RB74s? I've previously had RB74s and didnt really have a problem with them cold. I just had to remember to stand on the brakes at the end of my street, after that they were fine. From what I have found out, the DS2500s are a better pad for everything else. Just cold braking...

So really all Im asking is. If you have had RB74s and DS2500s in your car, for cold braking which was worse or better.

Thanks.

I've run RB74 and am running DS2500 on street now. And honestly i'm not impressed with the DS2500, they have no 'bite' maybe i've got a bad set. Don't get me wrong they stop me fine, but i have to put a bit of pressure on the pedal, even if warm.... where as when i put DS3000 in for track days, they bite nice and hard... doesn't take much pressure on the pedal.... but maybe i got a bad set?

The RB74 i found the same as you, hit them the first time and they are average, but after that they are ok...

I think i'm going to give endless a go for street pads when the DS2500 are out...

Well I replaced my RB74's with DS2500's. I found the Ferodo pad to be quieter, work & recover better at high temperatures, work better from cold & have good feel.

The key is to bed them in properly. If you don't you will suffer from the maladies listed above.

They are a better pad than the RB74.

oh. i can confirm this lack of bite. i have them on the rear of mine in ap 4 pots. and performance friction carbon metalics in the front.

for the life of me i cant get the rears to lock.

hence my master cyl thread

thays with 50/50 pressures. the pfc in the alcons just work to well. but im gettinfg some diferant rears with bigger pistons so theres more pressure aplied to the pad. curantly ive got 41.3/44.5 front and 27/27 in the rears. changing to 30/34 in the rear.

i want to get it to lock up so i can tune it properly. rite now all it does is cook the fronts cos the rears just arnt being efective at all.

any idaes?

I personally think the DS2500 are a great pad, had no problems at all. But my car barely sees the road more than 5 times a month, so anything brakes better than my work car :nyaanyaa: .

On the track the DS2500 worked VERY well, i was very impressed.

I have the 2500's... yeah not as much 'bite' as normal street pads but they are very linear... push harder and you slow down more;) didn't give me any problems at PI and I used them more than I should of because I was scared! lol

I hate spongy, bitey pads on the street... euros always have that soft peddle feel, I don't like it... and they tend to be much more dusty

Why put in a caliper with larger pots if you are already having issues with a lack of rear bias? It will only make it worse.

Check the pads aren't glazed & try removing some pad material fron the area closest to the hub ie increase the effective working diameter of the pad.

I've also had the ECB red stuff recomended, along with a halk pad, cant remember which one?

So lets throw them in there too. From what I have found they are all about the same level. With maybe the DS2500 being a bit more track friendly than street friendly.

I thought i bedded them in properly, same way i usually bed in pads, go out do some big stops, get them cooking, then let them cool down without braking.... usually works.... Do you think i should try roughing them up and bedding in again? Maybe i'm just used to the bityness of the DS3000s

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
