Re: Classic Disk Brakes

Looks like a very nice car. At the very least I would have the BTV working if you are going to drive it while you decide what to do on the discs. Once the BTV is working you can then decide if the original brakes are that poor. Without power working and with the low ratio on the BTV the brakes are really not capable of much.

I will let others get into the pros and cons of changing to the disc brakes but am wondering about the booster master they show as part of the kit. It appears to be a conventional tandem or dual piston setup but the booster looks fairly short compared to the universal units from ABS or MPB most are using.

I would ask a lot of questions as to how they want that installed and where. If in the factory spot in place of the BTV then is it able to be used with the existing 1:1 pedal ratio or, as I suspect, actually needs the minimum of a 3 or 4:1 ratio the other modern booster/master combinations need. The pedal ratio change would be something you will have to figure out as you have probably noticed if you've been following the various posts.

The booster diameter and length is critical if installed in the original spot as is access to fill the reservoir. Depending on how stock you want your car to look, it will stick out like a sore thumb when moved to the firewall and may require some other engine side changes as well.
