Other Wilwood brake options for ERA 427

[lippy]

Aside from the big brake option ERA offers, I know Doug and others have used SSBC calipers to improve braking. I was tooling around on the Wilwood website and noticed other options that *should* fit a '75 Camaro, and therefore an ERA.

The ones I checked out are:
- Dynalite 4-piston/12.19" rotors front kit, $800, requires some basic spindle mods (Wilwood High Performance Disc Brakes - 1975 Chevrolet Camaro - Front Brake Kit No.: 140-8582)
- D52 front caliper kit ($400). Wilwood says it's a direct bolt-on replacement for stock calipers (Wilwood High Performance Disc Brakes - 1975 Chevrolet Camaro - Front Brake Kit No.: 140-11291-BK)

Has anyone looked into these, or used them?

Your first Wilwood brake kit is basically the same one I have on order for my Hurricane except mine is for Mustang II spindles. Wish I could tell you how great it is but it's been on order for two and half weeks now. But it looks good on paper!
I did notice yours has an offset of .28". Don't know if that will make a difference for you or not though.

I have the dynalite 4 piston on the 12.19 roters, then switched to the 6 piston, it was a big difference, and used the 7/8 front master cylinder, with a tilton balence bar works very well. The 6 piston will bolt up to your 12.19 roters.Just make sure you do the embedding process on your pads.

Is that the master cylinder ERA provides, or a different one? Also, did you have them mod the spindle and just buy and install the 6-piston kit yourself?

Thanks for the help!

The Dynalite don't offer much except for its rigid mounting. It's a small caliper with small pads. The Wilwood site seems to be down right now, so I'll take a look at the 12" rotor setup later.

The Wilwood kit with the six piston caliper is 140-10738. Couple hundred dollars more but the bigger caliper and sweep area of the pad is nice.

The new ERA fabricated uprights don't require modification, just a bolt-on bridge appropriate for the caliper. The other question is whether this is a bolt-on or pin-drive wheel system. The rotor hats are different.

I plan on using the five pin drive wheels. I think the brake kits come with the rotors, so would these work with your system? Also, what size master cylinder do you provide? Thanks!

The kit mentioned above has some problems.

1/ The small pad that the Dynalite uses. It has roughly 60% of the area of the GM pad.

2/ The wheel mounting face is about 1/4" further out compared with a stock piece. There may be tire rub.

3/ We'd have to make a custom adapter for the caliper. For one-offs, that could be a couple hundred bucks (for design and machining).

SSBC: bolt on and go. No mod's necessary, better braking than the GM calipers, and Summit Racing will have them on your doorstep in 3 days.

Yes, (1) is true, but wouldn't you get better modulation with 4 pistons, versus one? There is another option as well (http://www.wilwood.com/BrakeKits/Bra...Camaro&option=), which is the 6-piston kit with 7.3 sq-in per pad. For (2), I think the offset is -0.28, not 0.28, so it is about 1/4" in, which should provide more wheel clearance. For (3), I was under the impression that you use a stock spindle, which should accommodate these kits. I must be wrong there. Thanks again.

A little, but the real advantage comes when the leading piston is smaller than the trailing piston to better distribute force over the entire pad.

Still smaller than the GM, at 9.5 sqin.

You might be right, but I've seen the drawing of what I suspect is the hub that they use. The wheel mounting face is moved out. I will check to see whether there's a different part though. It would be a big help for other applications.

[strictlypersonl]

I actually ordered one hub (270-104388) for inspection. If you can find any specs for the hat, that would be good. I couldn't. I need the hat/rotor offset to model the assembly on our upright.

My preference is still the Superlite-style caliper on a 1.25" wide rotor, rather than the wimpy .81" design.

[Le Mans]

Also I wonder would'nt the superlite be the best solution? In my kva GT 40 It offered a superb performance, While those dynalites at back with separate handbrake calipers. Altough the 15' rims Have limitations with wrong offset. Do you Have experience What willwood brakes 15" Halibrand replicas accept?

[strictlypersonl]

We've used the Superlite calipers (or their equivalent) on our cars with 15" wheels. It's tight, but they fit with the 12.18" rotors.

If you PM me with exactly what specs you're looking for, I'll call Wilwood and see if I can get them. Thanks again.

Hey guys,
I got my brake kit today from Wilwood. Mine is for Mustang II, kit #140-10440. My hub is #270-10442. In playing around with it, I see that a Trigo adapter does not fit the hub unless the dust cover is removed.
lippy, I think the kit you are looking at has the same dust cover. The adapter does fit with the cover removed. I may look at having a cover made that isn't so tall or rounded.
Or maybe just use the Trigo dust cover, though I'll have to see if it actually keep the dust out of the wheel bearings. Anyway, food for thought.

Sorry this is a little late but I think its good info
A 12.75 x 1.25 rotor and an SL6R will fit in a standard 15” wheel if you work out the spacing. I have done it on both an ERA and SPF

Nice Jason! Does that set up add anything to the overall track width?
