RestoRod 100-6 Seeking Guidance... Brakes to Start

Hello all! I'm new posting here... but have been reading posts for a while.

I have a '58 100-6 BN6 that I am bringing back from the dead (true barn rust bucket). Jule Enterprises has done the frame and started on the superstructure. Putting in a bored and stroked Ford 302 (now 331 with 400hp), Keisler Tremek TKO 600 5 speed, and narrowed Ford 8 Inch rear end with TT limited slip, .355 gearing, and Explorer disc brakes (fit in a 15 wheel).

I just ordered Dayton Wire Wheels for four corners - 'lip-laced' 15x5 D459s for front and special-order 'lip-laced' 15x7s for rear (15x7s will look 'stock' from side, fit within stock fenders, but will hold more meat in tubbed wheel wells).

Need help / guidance / suggestions specifically on brakes...

As stated, the rear end will have relatively recent Ford Explorer (equivalent of 2002 vintage) single piston discs with cable emergency that fit inside 15 inch wheels. I want to do something to beef up the whole system (electric booster? - Mustang perhaps) and front brakes in particular.

Thinking of doing 4-piston Toyota calipers, and heard Porche 11" rotors are a good fit....

Any thoughts..? Anyone know how to get to Norman in Laguna who used Porche vented discs on his 100-4 (https://www.britishv8.org/Other/NormanRest.htm)?
 
Also, looking for an authoritative source for the bolt pattern for rear hub to axel - need to advise rear-end builder (Currie) so they can machine axels and rotors...

Thanks!
 
See now, that's the joy of doing a modified car; you get to learn all these things as you go :wink:

For the rear end, have them do the axles in a 5 on 5 pattern, and the K/O hubs will bolt right on__you'll be able to use off the shelf replacement parts in the future.

If you can find rotors that fit the stock front hubs, fine, or I seem to recall that some smallish Lincolns used a 5 on 5 wheel bolt pattern, so maybe you can juggle some bearings around to use those front hubs, and then use a rear wheel splined up up front too.

Tim (cottontop) on here has built, and is building a Ford powered Healey, so he'll likely already have blazed some of the trails you're wanting to go down.

Out of curiosity, what is the VIN of your BN6?

Mine is BN6L-942...

I recently went with the well-laced Daytons:

Randy,

Thanks for the note.

I bought BN6-L/2734 (BMIHT #2004/3094) from Ross Campbell in Canada this last Fall - from pictures... He wanted me to see it in person but couldn't because of work. Ross is a long time Healey guy and has (had?) two others - he'd bought this one many moons ago to restore for his wife and didn't get to it.

I actually still haven't seen my car...

I had Martin Jansen, proprietor of Jule Enterprises, pick it up and go to work on it as soon as the snow melted this Spring (so Ross could get it out of the barn where it was stored...).

In regards to the 5-on-5 wheel bolt pattern, thanks! If you know it, can you also share the relevant bolt dimension (diameter / thread / length of protrusion from before the installation of the hub)? I can probably get this from Martin next week sometime if you don't have it handy...

The two keys to my 'resto-mod' are:
paraphrasing from the Six Million Dollar Man, "make (it) better, faster, stronger, (and safer)"; and
make it from parts that meet that criteria, but are easily obtainable / modern standards - none of that newly discovered rare-earth-metal, Un-Obtain-ium!

Have become aware of another 4 piston caliper. The Toyota calipers previously recommended are from an '80s vintage 4Runner, and though cast iron are said to weigh about the same as the stock Healey calipers (good for unsprung weight considerations). The new option that I read about last night is from the 90's vintage Mazda RX7 sport model - also fit in 15 inch wheels (key given my order to Dayton last week), are Aluminum (could help offset likely added weight from vented rotors), and cost less than the Toyota parts! Will be looking into whether the dimensions will fly and are an improvement over the surface area covered by the stock calipers and/or are comparable to the Toyota parts...

In regards to the Porche 11 inch vented rotors, from what I can tell they was chosen by the 'path-finder' here (Norman in Laguna, CA) partly because the rotor 'hat' fit well with the stock hub - new holes had to be drilled for the Healey bolt pattern (not a real big deal - had a small manufacturing business in a prior life so know how to talk to machinists and get things done reasonably - cash and not being in a hurry can be a big help).

I grew up in So-Cal (Newport) and wrenched a little on boats and dune buggies in my youth where I learned the value of reliability and easily accessible parts (nothing like a being in Mexico with a broken throtle cable), and hot rodded a Bugeye just after college - Ford 302 / Ford C4 slush box / Ford 8 inch rear-end. Always wanted to do a 'Big-Healey' and now I am - only this time I am letting someone else shred their knuckles... mostly becasue I don't have the time.

Thanks again and cheers!

Dear Mr. FrankenHealey,

You are the second person who has recommended the Wilwood solution today...

Will they fit in my 15 inch wheels? Paul F. of ModifiedHealeys suggested the Wilwood solution today as well, but couldn't confirm the combo would fit under my wheels. I assume the pictures are of your car - are you running a 15 inch wheel?

Thanks!

Hey Ian,

Are you coming to the "Nasty Boy" dinner at 19:30 on Tuesday 8/31?

Hope to see you there. I want to see the "Uncobra" again. My last time to see it was 32 years ago.

Tim
 
Ian,

Have been a fan of your car since I read the build on BritishV8. Am going to look good and hard at the Wilwood solution...

Tim,

Thank you for the warm welcome to the online Healey community!

Everyone that has reached out to me as a product of my posts have been very gracious and helpful.

Thank you all!

Regards,

Mark
 
Mark,

Thanks for you kind comments on the car.

I'm now building a 'little' accessory for the Healey having had some unpleasant experiences going to events and competitions. These include a trailer tyre blowout at speed and driving in convoy with my wife's Land Rover full of tyres and tools is also pretty sucky. So we decided that we wanted to travel together in one vehicle that should be of a period nature so I needed a classic transporter. The old team transporters are now going for BIG money therefore it's a case of build it yourself!

Buy one of these, not pretty but has the same lines as a classic Dunhill lighter.

Then Photoshop it a bit

Nothing's much to scale but I'm sure you'll get the idea :jester:

Cheers,

Tim,

I am not only coming but got the venue changed to somewhere with good food. The car will be there with the latest cooling mods.

Cheers,

Ian

We'll compare notes. I'm bringing a bunch of pix of my latest series of mods including my 24" wide radiator, R&P, 4 SUs, EDIS, and A/C.

See ya in 10 days.
