My whole braking system - thinking out loud

[Alvin]

You've got my attention.

I did not realize that the Impala rotors were that thin. I had assumed (incorrectly) that they were 1.25.

Are the Lincoln rotors available in drilled/slotted? Whats the application? Turning an axle down is not a problem on my end.

[Captainfab]

Yeah those would work, but they are just an aluminum single piston caliper. Just an aluminum version of an OEM caliper I believe. Weren't you looking at the dual piston calipers originally?

I believe the lincoln rotors are available drilled and/or slotted. I'll have a look.

I realized after I posted them what they were and went back and removed the link from my post... they are not what I'm after.

Looks like Summit has them as well, and they are the same as the ones I planned on running for the front, and a decent price.

those summit ones say bolt spacing 5 x 4.5

[Captainfab]

I went to Summit and changed the application to the MarkV which is the correct application for the 5 x 5 rotors and they are listing the same part number as the ones for the LTD which are 5 x 4.5. Might have to give Summit a call and see what's up.....

[smashingchuck]

Well I looked them up for several different years and it came up with the same one every time... wouldn't be the first time Summit had the incorrect info on their web site. I'm *guessing* it really is 5x5.

http://www.wheeltool.com/info/5bolt.html

[JW76]

it said 4.5 when i clicked on the application section there... but mine are 5x5 and they are for the 77 lincoln mark v so if those are for the same car then i would say that they are 5x5... a little confusion here and there keeps it interesting!

[smashingchuck]

So are you going to call them? I've got the time right now.

[Captainfab]

If you have the time go ahead, I've got to get going to an appointment. Let us know what they say......

They said that that is the incorect rotor for that application...

[smashingchuck]

Anybody know anything about these guys? The website seems kind of hookey, the prices aren't the best, but hey do make both applications (78 c10 for the front and 77 Mark V for the rear). I have yet to find a company that makes both rotors in a slotted/drilled set up.

I can also get the Power Slots for both the front and rear through Summit. They are $125 more (for all 4) for the Power Slots compared to the ones listed at the top.

Anybody ever have any trouble with drilled rotors cracking? It seems the more I read about these high performance rotors the more I think I might just want to go with a slotted one.

Have you ever had slotted rotors? I had the powerslots on the front of a 97f150 and after a while, they started making a humming noise and created slight feedback you could feel in the steering wheel. They weren't warped or anything like that, it was just a factor of the slots. I didn't like them which is why I'm going with regular rotors on my project. Plus aesthetically, i don't think they look good on our older style truck. Just my 2 cents.

Nope I've never had anything that had slotted rotors... Sounds like I might want to steer clear of them all together.

I have found another rotor that might work on the rear. It's the front rotor for an AWD Astro Van. They are 11.61" diameter, 1.29" thick and they have the 5 x 5" bolt pattern. The only drawback is that they are kind of deep.....1" deeper than the Lincoln or Impala SS rotors. So that may present some issues in fabricating a caliper bracket, don't know just yet. I have a parts Astro here that I'm going to pull a rotor off of tomorrow so I can mock it up and see how it looks. Do you guys have any thoughts on this thicker rotor?

That rotor sounds promising. Kudos to you CF for pushing stuff like this forward & possibly helping out the rest of this group in their search.

[staggerd86c-10]

ok, i have a question about this because ever since i saw those d52 claipers i have had the same idea about using them for the front and rear of my truck. I would like something like the blackbird kit for the rear of my truck but all i would need also is the brackets for the calipers. I have always thought that the blackbird kit used the same front rotors in the rear and clocked the calipers just like the fronts. I dont care too much about the slotted/drilled rotors but i do want a 4 wheel disc brake conversion.

[smashingchuck]

oppps... I was thinking they were mounted slightly higher than that. See what happens when your shop isn't at your house?

[kvn1011]

Quick question, will this new bracket to be work with a 72 rear end?
This definitly sounds promising

[suttoncurt]

Wow - just found this - good work everyone , Captin Fab , ill take a set of the brackets when we get this figured out - Im assuming this will be a weld on bracket?

[lolife99]

Here's a pic of the D52's on a set of Belltech 3" drop spindles.
They are positioned very close to three o'clock, on the spindle.

[Captainfab]

The caliper brackets that I will be making will be a bolt on assembly that will fit all truck based 10 and 12 bolt rear differentials from '64-'87 and possible as new as '98+

Yes those are close to 3 O'clock....in fact in that first pic they look like they're towards 3:30 a little. Did those D52 calipers fit the spindles without issue? Did you purchase the calipers in a kit with pads, hoses,etc? Just wondering if there could be any issues with parts store pads in these calipers. I know they're supposed to fit and Wilwood parts are generally real good quality, but......

Fingers crossed on this set-up. This would be a good one for the group here!

I bought the calipers from Jegs.
The rotors and pads came from SSBC.
The only thing different,... is there is no "spring clip" to secure the pad to the piston bore,... since the D52's are dual piston calipers,... instead of a single piston caliper.

The do look like they are clocked closer to 3:30,... but I had the front up on jack stands when these pics were taken.
