Brake rotor recommendations ('70)

[denizen44]

With these new solid wheels, front brakes get immensely hot.
I want to lessen the heat buildup: is it worth getting slotted/drilled rotors?
Has anyone tried them?

Welp, I finally decided to go ahead and give those 'high performance rotors' a try....

Package came in today, woot.




All I can say is: WOW.




My old rotors were still decent but below 1", whereas these new ones got plenty of thickness to go!



I love the fact that they are painted where they would usually rust!




Drilled and slotted!



New races!! Yayz.

Shouldn't have too much trouble installing these, most likely keeping my current 2 year-old bearings.



Made by StopTech.



These are asymmetrical and can't be swapped. I think the color difference is on purpose.



27 pounds each. Package was heavy as HELL!



More to come when I install them!

I hope they work, but I was going to comment that slotted and drilled rotors are a waste of money for a street car. I hope that they work out for you. They sure look nice.

What data do you have that says they are heating up a lot? Having trouble with brake fade?

Yeah well I thought so too, but they were a reasonable 75 each.

No fade, but I was getting sizzling hot wheels after a city ride, something that did NOT happen with the previous set of wheels.

I am positive these will stay cooler.

I hope so. Please let us know.

Did some brake work today

First, safely jack the car, then unscrew lug nuts.


Set aside...


Old rotors. They still had a few more years I'm sure...


Detach caliper... Set behind, make sure not to stress the brake line...


Remove dust cap, cotter pin...


Remove nutlocker and center nut, then pull rotor out, revealing a greasy spindle.


Take out outer bearing...


Rear side of rotor, where the old wheel seal is visible in front of the greasy inner bearing.


I'll be keeping those bearings, they are young and in great shape.


This works well to clean up the parts. Spray, wipe, rinse, repeat.


Done cleaning.


I managed to save these two old seals! (Wink to kev! )


But I used new ones anyway.


Testing, this is where they will sit.


Grease it up, pack it full!


Grease up the race generously, then set bearing in place.


I used this raw steel cylinder to make sure I hammered the seal "flatly" underneath.


Done. Surprizingly hard to force in.


Cleaned the Spindle...


Gently push rotor in... It's also packed with grease.


Grease up the race, insert outer bearing, then washer.


Center nut, snug but not too tight of course.
Then the nut locker and cotter pin...


Now for the new brake pads...


Nice and snug.
(Normally this goes in before the rotor. )


Re-install outer pad and brake hardware...


Expectedly, with all this new hardware, the caliper's piston had to be pushed in completely.


Despite the previous operation, it's still a very tight fit.
One also has to be careful not to pinch the piston's rubber lip against the pad.


Tight fit but the rotor spins freely!


Now for the left side's outer bearing...


Washer


Nut, nutlock and cotter pin


Spins freely, all done!


Sexay!


Back on its wheels!


Test drive tomorrow.

I'm confident, everything went flawlessly!

Id give yourself plenty of stopping distance...I have slotted and vented on my Crown Vic and they dont do much performance wise, but the ones I got are US made and with the 5 spoke rims they look pretty. On a steel rim you cant see em...

But they may feel better because theyre new lol... My 73 could use some new breaks, anything would be better than the potatoes I have as brakes!

Tested the new brakes today, the stopping performance is honestly just phenomenal.... Did StopTech make the rotors you use?

True.. But my hope is/was that the front brakes and wheels don't become sizzling hot as before.
