I've never seen one. Speculation is that the (Dunlop) discs that where allocated for the 100/S needed to be used up (minimum order 100, less the 55 or so Sebring models).
If you wanted to do it, the front discs from a non MKIII 3000 are a bolt on affair. To use the MKIII's you'd need the swivel axle as well as the brake calipers, hubs/rotors, etc. I have 1960 3000 front discs on my car (non servo 3000 m/cylinder).

I installed the Dennis Welch adaptor version to the front of my BN4. What a difference in stopping power. The kit is not hard to install and all parts were supplied but a washer. There is no dust shield in the kit which for our low milege cars is not really an issue. The calipers for the kit are type 16 and may have come off a Triumph GT6. The rear brakes are still stock at this time.

You'ld have to be nuts to put those stinking disc brakes on an early car unless it's a trailer queen. I bought one of the first 3000's on the east coast and those brakes were about the size of six postage stamps. As an only car it was driven in ALL sorts of weather, including New England winter. Typical mileage on a set of pads was 900 miles, yes, that's right, nine hundred. To make matters worse, at the time, there were NO replacement pads. In desperation I had to buy TR3 pads and cut them down! Needless to say at around 16000 miles I traded it in for a reliable American sports car. Bob<hr></blockquote>
Not sure how anyone else takes to your comments, but it raises my blood pressure a little bit when a total stranger calls me "nuts".
I've worked on dozens upon dozens of Healeys and unless neglected (usually due to lack of use) the early discs worked fine. Certainly better than the drums. I've never heard anyone complain before about pads lasting 900 miles.
Funny how none of the road testers of the time ever noticed a problem with the pad wear. It should've been visible as a build up of black dust on the wheels.
But thank you for your insight, however tactlessly put.

I bought a 3000 new in 1960, after a relatively short number of miles the pads were completly shot. I took it back to the dealer who installed dust shields. After that, I used it for 16 years as a daily driver (sometimes) and never had a problem with excesive pad wear or stoping power.

Dave: I never changed my mind but I have gotten to a stage in life where I can have just about any toy I want. The stable contains the MGB, Miata, Corvette, a cobra replica, Suzuki Swift GT and a ZX2 Escort. My biggest gripe with the Healey was it's unsuitability to be an only car year round when one car had to make do. Richard: Glad to hear from someone who experienced the problems I had. My dealer never offered to install shields nor to replace the brakes as they were, in his words, "soft parts" and not covered by warrantee! Also my apologies to any and all who were offended by my original post but even after fourty five years those brake problems stand out as the biggest problem I have EVER had with a LBC and felt strongly enough to try to discourage anyone looking to make that move without considering the possible ramifications.

Bob,
I understand. I would surely not want a LBC for an only car. This old guy drives a Camry for reliability & comfort. I was just teasing you.

Bill Piggott shows a picture of one he owned with the four wheel disc brakes in his book "Austin-Healey; a celebration of the fabulous Big Healey" on page 78-79. He further states these were Dunlop systems, like the 100S, not Girlings as used on early 3000's. There is no mention of these specials in the Big Healey book by Bill Emerson. There must be at least a few around out of fifty or so, unless they were converted to std settups due to non-availablity of replacement parts during the "lean" years of the 70's.
I'm surprised there is not registry settup for these, as rare as they are.

Donald Healy America, 46 Sea Cliff Ave. Glen Cloove NY offered both two wheel and four wheel disc brake conversion kits for BN4 and BN6 cars. The part no. for the four wheel setup was H8249 and cost $396.00. This parts list was printed when MK II's were in production so I don't know how early they were available.
