Piney,

I believe that the calipers in your pictures are sold by Sierra. Not sure if they are still around?

Chris, the brakes work really well, however, I don´t track the car or anything. Pretty much zero pad wear, which is a little odd, since they must have been on the car for at least 20 years :O

Ron, thanks, yes that could certainly be the case, it seems Sierra bought the rights from JFZ in the 90s.
I know this post is about front calipers...my fronts are getting some paint at the moment...

Here's a shot of the rear.

Still waiting for a couple of pistons to appear.

Ciao!
Steve

STill not quite done with this brake job!

Replaced the front bleeder valves...and found out that they are too short! I can get at one fine, but the second one has interference from one of the 4 caliper bolts holding the two halves together!

Also pedal is way down at bottom of travel (15/16" unit) Solid once you get there and brakes work good! But more on this later.....

I need to understand what source we have for getting new long bleeder screws. Mine were pretty buggered up on the hexes, so want to put new ones on.....

Again, front stock calipers on a 74. Front bleeder screws. Part number if ya got it would be appreciated!
Thanks!
Steve

Yes Sierra Racing are still around, Larry Stock at Pantera Parts sells Sierra calipers with his brake kits so not surprising to see Pantera's so equipped.

PanTTera,

I used a similar bleeder, 3/8" hex and one is good, but the one up against the bolt is a no go!!!

After some more searching, I found some that were 10mm longer and a 9mm hex, more like the originals. If those don't work, there is another that is 18mm longer than the short ones that I have! They are coming from Europe.....

We'll see!!!

When I need to work on stock calipers (I avoid it if at all possible), I use a 3/8" socket on a 1/4"-drive breaker bar! Once the bleeder moves, it can be played with using an open-end wrench, but if it's stuck, you'll just round off the hexes with an open-end wrench.

BTW, some owners do not have the concept of preventive maintenance well understood. I had one rear caliper on a friend's car that would not bleed. So I removed the bleeder screw entirely, then stood on the brake pedal... no fluid came out. I wound up drilling out the passage in the caliper, AND in the bleeder screw. Must have been decades since anyone tried to bleed that caliper. The varnish was like JB-weld!
