A very nice conversion with a different take on the e-brake setup, take a look.

Good work Kelly!

Regarding E-brake, I used new stock TR6 cables from Moss; I machined a trunnion to thread onto the end of each cable and fit in the caliper ‘saddle’ to pull the e-brake mechanism. I used a 3/8” AN bolt - the unthreaded shank area. I think it is 4130 steel. Very strong. Drilled it with cobalt drill and tapped 1/4-28. I fabricated the brackets that attach the cable to the caliper from 1/4” x 1” cold rolled steel. Works perfectly. No modification to the cable necessary. Brake handle pulls up 4 - 6 notches for solid grab. Easy to adjust at caliper end as pads wear.

Also, I machined the caliper mounting brackets from 7071-T6 aluminum 3/8” thick. The alloy is much stronger per square inch than mild steel of the same thickness. Of course I upgraded the swing arm studs to 3/8”.

Here are some pix of the e-brake set up and my engine / cockpit. And yes, I know, I need to get the airbox I fabricated polished!

Thank you once again.

Cheers, Kelly

Hello TR fans, I have read your article, regarding the rear disc brake conversion, and would like to try this on my TVR 2500M. If there is an outlet for these brackets, could you please steer me in that direction. If that information is not available, please reply how I may receive the Cad file, or detailed sketch, so that they may be re- produced. Thank You, Tim

Hello all a bit of an update here. Got brackets machined and all not an issue but i did have an issue trying to source calipers, in particular the driver side caliper is apparently a rare bird. Cardone, rock auto etc are all out. I finally got one from stockwise auto. Also as the article states there was a change in disc calipers styles for the maxima mid 1987, i had the best luck searching using 1986 as the model year. If you do get a hit for a rear caliper and it is made by Beck/ Arnley i would take a pass as the caliper mounting brackets dont fit properly in the machined bracket. Cheers everyone and happy thanks giving to our friends in the USA.
