Powerslot brake rotors??

[latham83]

Hey i was looking into buying powerslot rotors and Hawk brake pads for my 1990 5.0..just the front though...
ya think they will give me really awsome stopping power over the stock ****...
im not touching the back brakes right now...
i think the rotors sell for 90 bucks a piece and the pads like 40 or so..anyone konw of anywhere cheaper? or anyone have those on??

 

[DansLmted93]

i have that setup.powerslot rotors and hawk pads a hundred times better then stock,forgot what i paid for the setup but i remember i bought them from Maximum Motorsports .

 

[flyinghi3]

i have the same set up too. hawk brakes and power slot rotors. got mine from brotheres performance.

 

[latham83]

wow cool guys...is it like freakin awesome stopping or what..even if i just leave the stock back drums how they are...its still like 10000 times better huh?
i cant wait...
so what all should i really buy...powerslot rotors, hawk pads, the regular performance ones right? and stainless steel brakelines..thats really all i would need right? and all that **** just bolts right up..no other mods? of course a good brake fluid i guess..what u reccomend?

 

[flyinghi3]

what i bought was just the power slot rotors, hawk break pads, and grip stainles steel brake caliper sleeve kit. i didn't get the braided stainless break line. they just bolt right one. also i didnt change my brake fluid, but if yours has alot of miles i woud flush it out and put fresh fluid in. they defenitly stop alot better and its very noticeable when your at the track trying to slow down from 120mph.

The rotors will not improve your braking. Actually make it worst since you have less surface area.

The pads since they are a more aggressive compound is what makes that brake package work better.

 

[latham83]

that doesnt make sense that they dont improve ur braking...of course they would...the stock rotors are crap..
but of course u would buy high perf. rotors and then put ****ty stock pads on either...

I was just going to say this myself..... They are mostly for looks, pads would make the biggest difference for STOCK brakes, upgrade to 73mm calipers and the difference will be much much greater. Drilled and/or slotted rotors are for old technology pads that produced gases which made braking suffer. Releasing the gases through holes or slots would improve braking....but not anymore, pad technology has changed since then. The only reason they are still made is because people buy them.

With the above quote coming from THE brake man himself, I would take his advice....

Slotted and drilled rotors help resist fade by venting heat and gas from the surface, which would be nessasary for a high friction pad.

Since your going that far, what about caliper upgrades, such as the 73mm SVO calipers, the same as the '91 Mark VII?

listen to matt. the rotors will actually hurt your braking. IMHO you should get the pads/sleeves/lines/fluid and just stick with a SOLID rotor. go check out matt's site about brakes. you will learn a lot.

edit: by solid i mean vented, but not drilled/slotted.

The man is right. The stock rotors are actually better than slotted/drilled rotors.

Crossdrilling was developed back in the 50's and 60's when brake pads produced gases. The gases needed to be disappated so thats what the holes were for. Today's brake pads don't do that so drilled rotors are useless.

The stock SOLID rotors have more mass and can absorb heat better. The best way to dissapate heat is to have more SURFACE AREA and also the vented design of the stock rotor helps cool them off.

So anyway, HAWK brake pads are a very good performance item, but i'd return the powerslot rotors and get some good ole quality solid rotors made by Brembo or such.

It's not the design of the rotor (solid vs slotted) that makes it crappy, it's the quality of the materials used.

FYI...i had powerslots. Warped them in a week. Put a set of Ford rotors on after and never warped them.

Slotted and drilled rotors help resist fade by venting heat and gas from the surface, which would be nessasary for a high friction pad.

this was true in the past, but the new pads are much better. it is actually the surface area of the rotor which absorbs the heat, therefore any reduction in pad-to-rotor contact (ie slots/holes) will reduce braking effectiveness. beyond this slotted/drilled rotors are more prone to cracking.

6" fart tips do wonders for HP also! Same with the 2 story wings!

Pads dont gas. Slotting and drilling look good, but cut down on the surface area as others have pointed out.

When you have a large enough rotor like a Porsche or Ferrari, those drilling and slotting is molded/cast with the rotor. not an after thought. The reason why the larger rotors do it is to lessen the weight - not something you have to worry about on your 10.84" rotors.

 

[latham83]

ok wow...i never knew any of this...sooooo..what the hell do u guys reccomend then if not powerslot rotors...what rotors should i buy and where are the best prices...
i should still go with the reg. hawk performance bads and stainless steel brake lines right?
and well all of that do me wonders? i dont wanna touch the back brakes cause they arent that important anyway..and i dont know if i have the money for calipers..

Get some remanufactured calipers for a Lincoln Mark VII, just make sure they have the steel pistons, and then bring your old calipers in for the core. Some stock replacement rotors should be fine, but if you do a lot of heavy braking go to ford and get rotor, or like Mike said above, some Brembo replacements.... Top it all off with some good pads, and if you really want some stainless line, which will make your pedal feel a little stiffer...

I went with bigger calipers (73mm Lincolns), 93 Cobra MC with Maximum Motorsports kit, SS brake lines (3), SS caliper sleeves, Power Slot rotors, and flushed system with new barke fluid. Works great exept for my right front which locks up too early. Once I get that problem fixed the upgrade will be worth it!!

Make sure you bled the brakes good enough. If you are using used calipers, that could be the problem as well...

 

[latham83]

alright...now things are getting confusing...from what i read...theres absolutely NO advantage over powerslot rotors? ok then if i bought stainless steel brake lines, hawk pads, and good brake fluid..JUST for the front brakes thats it...and a new plain rotor..would i have pretty nice and non squeaky brake power??? i just dont understand why like i always talk to ppl that run slotted rotors and i even drove their cars and it seems like it stops better..i dunno..whatever... what rotor do u sugest..i dont think im buying calipers..dont have the money.

 

[custom89stang]

what 73mm calipers will bolt directly to a fox mustang front? You said
a Lincoln Mark VII? what year? what should i say to NAPA/Schucks?

And are the calipers longer horizontally or vertically? i noticed the calipers i currently have (stock) still have an inch of room between the bottom of where the caliper starts and where the rotors center is.

4. Upgrade the front calipers to 73mm SVO units. Get the 73mm calipers with a steel piston if you can. They are usually denoted in the part numbers with a "S". If not the phonemic will work fine on the street. Get the calipers for a '91 Lincoln Mark VII for a direct bolt in (other 86-91 Lincoln's should all have the 73 mm calipers, 86-91 Crown Victorias and 84-86 SVO 4cyl Turbo Mustangs). Here are the part numbers the remanufactured Bendix parts:Left caliper : R55247S Right caliper: R55246S
