I have a 89 vert that I am going to get new brakes for ( all new rotors & pads). I plan to get new Brembo Drilled Slotted Rotors off of ebay. I think I am going EBC Greenstuff Road/Sport disc brake pads. When picking out pads Tire Rack shows front brake pads for models with solid rear rotors and ones with vented rear rotors. What do I need? What do you guys think about EBC Greenstuff pads?

 

i think there were only solid rear rotors... but i could be wrong... but EBC Greenstuff is some awesome chit... but i've heard complaints about excessive squealing... and possibly eating up rotors and such. but it should be awesome.

 

if you have a 5 lug car you have vented rear rotors. if you have a 4 lulg base withOUT 4 piston calipers up front then the rears are solid.

 

no not quite.

if you have 4 piston front calipers on an S5 you have vented rear rotors. If you have single piston front calipers on an S5 you have solid. your vert should have vented rear rotors.

 

So an S5 vert does have vented rear rotors? How can I tell by looking at them to make sure? How can I tell if I have single piston front calipers or 4 piston?

 

You don't need those, just get regular rotors.

 

Why would you say I don't need them? I am getting all 4 new rotors for $200.

 

Ha, looks like we're going for the same thing - I'm redoing the brakes on my 88 Vert as soon as all the parts get in, hopefully this weekend! Ebay drilled/slotted rotors (162 shipped), Hawk HPS pads (the best bang for the buck in the braking industry, FAR better than EBC Greenstuff IMO) from www.SPLparts.com, Technafit stainless brake lines from SPL as well (Can't say enough about these guys, best prices, best service, period), and a complete flush with Castrol Dot 4 fluid. Also goint to polish up the front calipers a bit and squirt some paint on the rear calipers while I'm in there.

You have vented rear rotors and aluminum front calipers, if anyone asks! You don't NEED the drilled/slotted rotors, consider them as a show item only. You likely won't stop a foot shorter with them than you would with the "normal" rotors...they're just pretty. Make sure the ones you get are zinc coated so that they stay bling.

 

I already responded to this question in the suspention/brake section, but I'll put it here too, I guess. The EBC greenstuff pads are decent pads for the street. From my experience they don't squeal, but there are others on this forum who disagree. The main problem I have with them is that they tend to fade, especially in very spirited driving(ie. hauling *** down back-country roads.) I have noticed at other times, such as when slowing down from the highway, but not too bad. If you aren't planning on doing any super fast driving, they should be ok, but there are better. I've heard good things about Hawk HPS pads from other people. If you do drive it fast and seomtimes have heavy braking, you might try Hawk HP Plus pads, which are more track worthy. Anyone here have experience with either of those pads?
Edit: While we're at it, what brake fluid do you reccomend? Racing beat sells Ferodo brake fluid for $16 for a half liter bottle. Is it any good?

 

Well, it looks like they're about 45 minutes from me, so I might be getting stuff from them, too. What are their prices for the brake pads and SS lines? I didnt see it on their website.

 

i have also heard that the only olty rotors that EBC pads wont eat are EBC rotors so take some caustion there

brembo does not make cross drilled and slotted rotors for our cars which means that some one took them and drilled out the factory slosted rotors which is really really bad

i have brembo blank rotors ($30 for the front $28 for the rear) and hawk HPS pads and while i was doing that i put in some goodridge SS lines and speed bleeders and i belive that i have awsome braking power now i love my simple set up

BTW im running valvaline DOT 3&4 synthetic fluid

 

What do you guys think about PowerSlot Rotors? I see them at http://www.rx7store.net/productgroup...05&1=238&33=16 The only thing is that it says 86-92 Turbo, will they fit an 89 n/a? What is the difference? Do the Hawk HP+ pads put off alot of dust?

 

I have HP+, it's ok, not the hardest gripping pads I've tried, but not bad. Not much noise from them, and not much dust either.

But then again, I'm suspecting that my braking system isn't too great, perhaps master cylinder, or brake booster problem. I also use Valvoline synthetic brake fluid, DOT4, pretty good stuff.

 

Turbos have larger rotors, and possibly different calipers, I'm not sure on the specifics. To my knowledge, they won't fit on N/A brakes. If the rotors actually are x-drilled, I woudn't get them, but I kinda doubt they are. I don't think Brembo makes many true x-drilled rotors any more, as they seriously compromise the integrity of the rotors. They are much more likely to for major cracks than other rotors. I think what most companies use are "dimpled" rotors. It helps evacuate the hot gasses, and gives it a cross drilled look without actually drilling a hole straight through. I'll try to find a link about it.

 

Woops, Brembo does mostly make x-drilled rotors. I couldn't find **** about what they make rotors for on the site, though. They didnt really have anything about rotors, just brake kits. Anyway, here's a quote from the power slot site : "When you drill a rotor you weaken it and cause stress points that can lead to cracking and ultimately failure"

I've seen it happen to Brembos on a Ferrari 360, and it pretty much looked like that picture.

 

Does anyone know where the best place is to get a set of good brake rotors at for an 89 n/a rx7 is at?

 

do a Froogle search on Brembo brake rotors, i found a few sites that sell them for a good price.

 

i would go with the slotted rotors or just blanks at best and stay away from the drilled. i'll be doing my brake system as soon as i get my body work done and gather all the parts. i have a set of Hawke HPS (tirerack.com)...i haven't installed them yet but i read lots of good reviews. bad things bout drilled rotors keep coming my way so unless they are the top of the line no imitation stuff, i personally will stay away. i think the imitations are more or less for show.

 

Brembo makes OEM replacement rotors that sell for $53 each at Tire Rack They're only for 5 lug wheels, though.

 

about the PowerSlot Rotors, I saw the ones at http://www.rx7store.net/productgroup......1=238&33=16 The only thing is says that it will fit 86-92 Turbo, will they fit an 89 n/a vert? The reason I said 89 vert is bacause I was re-reading the "Specifications and Features" https://www.rx7club.com//showthread....hreadid=249616 and I saw under the 1989 Chassis section under "Brakes" it stated "10.9-inch ventilated frount discs with four-piston aluminum calipers, 10.7-inch ventilated rear discs: GXL, Turbo, Convertible". So I guess the PowerSlot Rotors for a 86-92 Turbo, will fit an 89 n/a if it is a vert. Has anyone replaced their brakes on an S5 vert to confirm this?

 

Uhhh, a little lesson here (and why people don't look at the sticky at the top of the section about what FC came with what is beyond me)...

Turbo's have the same brakes as the 86-87 Sport, the 86-90 GXL, 88 GTU, 88-92 vert, 89-90 GTUs (but not the 89-90 GTU), and the 91 coupe with both A and B packages.

So your comment about turbos having bigger brakes than non turbos is incorrect. Better said would be that Turbos got the same brakes as most of the non turbos, except the base, SE, Luxury coupe,89-90 GTU and most of the 91 coupes.

And back to the subject at hand:

Cross drilled brakes for a street car are just stupid. The stock brake rotors are more than enough to provide stopping without and funky cross drilling and weakening of the brake rotors. The only (and I mean truly the only) advantage a cross drilled brake rotor for an RX-7 has, is that it makes the unsprung weight slightly lighter at each corner. But this advantage is way way offset by the diminished brake rotor life as well as brake pad life or potential for fatal brake failure.

 

again, they are the same and completely interchangeable.

 

Since they're mostly a Nissan place, they don't list any FC stuff, but they can get it through thier dealers. Their price on HPS pads was the CHEAPEST I found in the country, believe it or not. They're about 45 min from me as well, and well worth the drive. They are having a BBQ tomorrow and have a sale on Hawk pads, so if you stop by and buy some not only would you get a discount on already low prices, but also free food! Try getting anything free from tirerack except stickers and non personal emails.

Give the guys an email, sales@splparts.com, or give them a ring, they'll hook you up.

I'm going to them tomorrow to buy an Innovate LM1 wideband setup, too!

 

Thanks alot Icemark for setting the facts strait.

 

is this a good dealplease give answers fast i need new brakes so im upgrading the rotors to so are these good i know they are slotted and drilled but i really want them i like how they look http://cgi.ebay.com/ebaymotors/ws/eB...category=33564
