Does anyone have any info on the single piston caliper "V-Back" brakes? In the National parts Depot catalog, they list them as pre-Nov 1969 Calipers as a V-Back style, and post-Nov 1969 to 76 a different type of caliper altogether. I believe I have a set of the V-backs and I took them off of a 72 Nova. Maybe these weren't original equipment? I have been trying to locate a drivers side core, because the bleeder valve was drilled out and now the seat for the bleeder is history! I go to local auto parts stores and they look at me confused. I have been to many local salvage yards and have had no luck there either. Any insight would be much appreciated!

You might try this poor-mans trick to salvage your caliper.

Just drill the bad bleeder hole out and tap it for either a pipe plug or a suitably sized fine threaded bolt. Use some teflon tape and screw into place and torque down to a "good" feel. Also, leave a little tap taper in the threads, too at the end so the bolt or pipe plug will snug up some.

I have a rear brake cylinder that has a fine threaded bolt in it thats been this way for years and years with no trouble. pdq67

Here is a photo of a 69 caliper I have on the right and a later 72 or so Monte Carlo caliper on the left. It doesn't show well, but it has a V shaped casting lugs on the back side, pointing up on the photo.
This might be what they are talking about.
Any numbers on the caliper?

If the photo does not appear, it's because the server it is on is down.

The bleeder can be fixed by drilling and tapping for a replacement bleeder. They are small and use pipe threads. The new seat and bleeder just screw in after tapping with a pipe tap. I think they are 1/8" pipe thread.

You can get them at the auto parts store.
Or call Speedway Motors 402-474-4411 ask for #835-2200063 they are about $4.00 each.

pdq67, how do you bleed the brake after you screw a bolt in there?

It's just a normal two man operation. Last time I did it my son pumped the brakes as I loosened the bolt slightly to bleed. Worked great, although I must admit that if I woulda known that bleeder repair kits are sold, I woulda used one if I could find one instead of the bolt.

Heck, they probably weren't around in 1985 out in the boonies of central MO at that time. pdq67

Those bleeder repair deals are used on all the aftermarket calipers like willwood. That way the seat for the bleeder does not have to be machined into the caliper.

My Lola uses a Girling caliper and I had to use them on those calipers.
