Triumph TR6 Rear Disc Brake Conversion / brackets only
I have completed my TR6 rear disc brake conversion. I had a CNC Machine shop in Columbus, OH cut my caliper brackets out of ½" steel. To keep cost down I ordered extra sets hoping that others might want to follow suit and not go through the engineering progress on their own. The brackets were designed on a CAD system, modified through test fittings in aluminum and then CNC out of steel.
My design incorporates an e-brake, keeps the spring location, and keeps a gas shock modification with very minor modifications using simple hand tools.
The system fit very nice under the swing arm, clearing all obstacles for mounting and arm movement. Only a small quarter size round out is needed for service access to one mounting bolt head. (See pictures attached slide 1) The e-brake cable can be sources from LOKAR. (U cut to fit)
Once you have the brackets, you will need to source the disc brake calipers, rotors, misc brake lines and hardware like (12) 2" studs.( to replace stuck studs, too short with the bracket)
I don't want to go into the parts business.
The brackets are designed for 1987 Nissan Maxima rear disc brake calipers w/hardware w/e-brake, and the rotors are 1984-94 Nissan 240sx.
There are other Nissan models that used the same type of caliper like the 200sx, Stanza, 240sx, Maxima, and some 280zx, but be careful as Nissan changed systems all through the model lines. The e-brake cable can be sources from LOKAR. (U cut to fit)
If you have modified to a coil over system or don't care about the e-brake, the brackets will rotate and flip around for a top mount towards the rear of the swing arm.
(See attached picture slide 2, black is steel version)
The bracket set (2 brackets) are priced to cover cost only, priced at $160.00, plus shipping costs
(I painted fat black to slow down rust)(I'll include how to Power Point with links to suggested resources) (Also disclaimer)

Thank you for looking!
This steel bracket, specified rotors and calipers do work with stock steel wheels.
I pulled the Panasports off, installed my spare steel wheel and checked for clearance.
All clear with ample room for stock wheels. You still need to double check your wheels and always be safe FIRST!
The 15"x7" Panasports have 0mm offset, 3.9" backspace, whereas the stock steel wheels run +12mm offset, 3.5" backspace.
See attached pictures.

All have sold! Thanks to BritishV8!

I have the CAD files that I used in making the TR6 rear disc brake brackets.
I have various file formats so if you can locate a CNC Shop, I think they will be able to turn you out a set of brackets. (ASC, DES, Dra,DWG,DXF, WRL,STL, IGS, STP,VDA, even a jpeg for reference)
This jpeg attached is without information just to give you the idea of quality.
These are free for the asking and an email account that can take some large files.

Don, would also appreciate you sending the CAD file (AutoCad DWG format is fine) for the disc brake brackets. Would also be interested the caliper part number. Email address is epeppy@hughes.net.
Thanks for making this available!
Albert, Ed
CAD files are sent and please post pictures of your rides and progress on your modifications.

More are being made!
I'm posting this with his permission.
A gent in Canada is getting ready to make a run of about ten sets!
A fellow TR6 has requested he turn out a set of brackets.
Francois has offered to make about 10 sets.
So, If you are interested, here is his contact information:
François Faucher
fr.faucher@videotron.ca

Check out his TR6 mods. I love the shroud cover.......that's HOT!
Had a machine shop make 10 sets of Don Watson's disk brake brackets, using his cad file, with his permission.
5 sets are already spoken for, so have 5 sets left in the run are up for grabs if anyone wants them. There brackets were made out of 1018 ½"grade steel .The cost is $145.00 for the pair shipped in the US.
Yesterday I was able to pick up the first brake bracket (from the machine shop) of the run. It took awhile to find someone competent to do the job right.
The photo's show that the outer edge ruff cut was done with a High Definition Plasma cutter, probably ¼ million for the machine. The holes were drilled and the center hole was milled.
There is one photo that shows where the Plasma cutter started and stopped on the outside of the bracket. This area does not need to be close tolerance. I will grind off the bump and clean them up before painting black for rust.
For further information, can email at waterhook@surewest.net or PM through BV8.org
Thanks to Don for making this happen, I'm just helping others as Don was there for me.

Update,
There are 4 sets of disk brake brackets left as of today out of 11 sets made.
So far these bracket's have been sent out to, 1 set to CA, 2 sets to Canada, 1 set to Norway, 1 set to SC, and 2 sets to PA. Monday morning the 7th set will be going to PA.
After the last set is sold, if people show enough interest, I can have another batch made up, but of course the more made the price does go down some.
Tha batch that is completed now cost $145.00 for the pair (2) brackets to ship anywhere in the US. Out of US is the shipping difference and labeled on the paper work "Parts for an Antique Car".

Update!
There are 2 sets of brackets left as of today! There is a pair going to KS this morning.
Update!
All the rear disk brake brackets have been "SOLD".
The last 2 set's are going in the mail today. One is going to Alaska, and the other to NC.
Thanks to BV8 and Don Watson responding to emails and sending out the word. Ebay wasn't even used ;-)...
I can do another run if more people show interest.
If you want a pair of bracket's email at waterhook@surewest.net and leave your name with me. To make it an easy secure transaction, I'm sending Paypal money request to your email for who wants them. Paypal is easy just follow the instuctions from the Paypal money request email.
Calvin
Update!
I have put in an order for a run of 10 more sets of disk brake brackets yesterday!
This coming Monday, the machine shop will let me know of a completion date.
There have been 4 inquiries for these disk brake brackets to be made, so there will be 6 to 7 set's available at this time of post left of the run.
Same price of $145.00 shipped in the US and more postage out of US.
For inquiries for the brackets, email waterhook@surewest.net
Calvin
Update!
The machine shop let me know the brackets are being plasma burned now!
There are 7 sets out of the 10 spoken for already, and 1 inquiry as of today!
Also had an inquiry to have these brackets made in aluminum 1/2" thick (for unsprung weight). I'm getting a quote for 1/4" thick steel brackets too. The only difference using 1/4" steel brackets, would be 1/4' shorter trailing arm studs, and 1/4" shorter caliper mounting bolts. A caliper bracket made in 1/4" steel is plenty strong, they use 1/4" for off road racing.
The 1/2" steel brackets are still $145.00 mailed in the USA. I will post a price when I receive the quote for 1/2" aluminum brackets, and 1/4" steel brackets. waterhook@surewest.net
Calvin
Update!
I picked up the run of disk brake brackets yesterday!
Will be painting them within the next couple of days + drying time.
There is some left up for grabs from this run still.
Received some pricing on 1/4" steel brackets and 1/2" aluminum brackets. Finding out if the machine shop is setup for the run, it's easier to get the 1/4" steel and 1/2" aluminum ones made and not have a full 20 pieces made. The setup time is what is costing the majority of the price, so if the timing is right, any one of the 3 brackets can be made. Steel takes longer to mill where aluminum can be milled faster than steel, aluminum does cost more. The aluminum will be all milled out, even the outside perimeter, not plasma burned like the steel ones. It would drive the price up more.
Mailed prices in the US:
1/2" steel disk brake brackets = $145.00
1/4" steel disk brake brackets = $135.00 per pair (not much difference in price compaired to 1/2").
1/2" aluminum disk brake brackets = $195.00 per pair.......much lighter than steel. Some have asked for these.
contact: waterhook@surewest.net or 74ls1tr6 PM in this forum.
Update!
I have 3 sets of brackets left of the kast run. They are 1/2 steel.
So they are up for grabs if anyone wants them.
The price is still the same in the post above.
Calvin
Update!
I have 2 sets left out of the last run of brackets!
One set Ken Schmidt here in Sacramento may want for his red TR6!
Next run of brackets depends on how many want them before a run will start.
This would be a good time for the aluminum 1/2", or 1/4" or 1/2" steel brackets made at the same time. It would be less expensive to run them at the same time, to cut down on machine shop setup time.

Update!
Ted in NC just bought the last set of brackets!
This set of brackets I was holding for Ken Schmidt here in Sacramento Ca, but said go ahead and sell them, and maybe get a set later.
So I can do another run of bracket's based on interest, so would need your name and e-mail to put on the list for the next run!
Contact : waterhook@surewest.net Subject: TR6 rear disk brake conversion brackets! If you read the posts before this, the price has not changed.
Thanks,
Calvin
FYI ....People out of the USA, I found that I can mail these bracket's which are under 4 pounds in the smallest flat rate box for under $20.00, was costing $40.00 to $70.00 any other way.
Update!
If this interest keeps going the way it has shown, will start doing larger runs like 20 sets (40 pieces) price could come down some for all. I didn't think there would have been such an interest for these brackets, was making some since Don Watson only made a few, I was one of the lucky ones to get a pair from him. I figured I could fill in just for others that wanted them since I have easy access to machine shops in my area "Well people keep wanting them". So I'll keep getting them burning at the machine shop. At this point I don't have up front cost until pick up date to pay. In the begining had to pay before starting. I don't advertize out of BritishV8.org for these brackets. It just goes to show how this site is growing so fast with this sport. "WOW". I personally wish I had more time to devote getting the whole kit together for eveyone so it would be easier for this conversion. Have had tons of fun talking to people all over the world with the same sport of interest and helping other with their cars.
I have had enough interest, to put in another order for 10 more sets of TR6, TR250, and TR4irs rear disk brake conversion brackets.
I e-mailed the machine shop this morning to go ahead and burn out 20 more steel pieces. Will get a confirmation of completion time.
So who ever is interested, "get your name on the list", they seem to move out in the mail fairly quick!
Mailed prices in the US:
1/2" steel disk brake brackets = $145.00
1/2" aluminum disk brake brackets = $195.00 (the more made at the time of the run this price could come down some for all)
Mailed out of US add $20.00 for flate rate box (cheap way for mailing these compaired to mailing in a different box)
If anyone wants a set of 1/2" aluminum brackets, let me know real soon, because when the machine shop has the steel ones setup, it would be less setup time to run the aluminum brackets at the same time (keeps the setup time down).
Contact: waterhook@surewest.net
Thanks,
Calvin
Have the brackets from the machine shop as of yesterday!
First set will be going out today to Jeff in WA who missed a set from the last run.
Sent emails out to people who were on the waiting list today!
"Get them Now"
Price is in the previous post, and contact information.

Thanks.
Marek
I can do another run of brackets if there is enough interest involved maybe 8 or 10 sets will work. Merek is 1?
I need a set in 1/2 steel, please.
John
Hi,
I'll take a pair.
Has there been enough requests for an order?
Thanks,
Joe
I'm getting ready to do an order here soon, my machinist has been pretty busy, so waiting for the word! I will post when its in the works.
The email on this thread is an old one and does not work anymore. PM me for the new one.
