Banjo Bolts?

the banjo reduces tension on the hoses. Not sure which series car you have, Later cars have Girling calipers so I would have a look at Jaguar, Volvo of the period, the banjos are just bolted on to the ends of the hoses

Did you check with these guys ? The bolts themselves should be British thread. I'm trying to remember the unions there at the calipers, if like the 'stepped' ends used around the master cylinder I agree, those I cannot find. But you should be able to get new unions and bolts that screw right into the brake lines.

Summit has tons of them, both English and metric. You just need to know the size and thread.

I have not been associated with the Mangusta, but make sure you get the proper copper washers for the inside and outside of the banjo.

And I’m not just
saying this because I’m from Arizona, and I want to sell more copper!

We used to get new copper washers from any local motorcycle shop. If you reuse existing washers, be sure you anneal them with a torch- in use, they progressively work-harden so eventually they begin to leak unless annealed.

Here is the style of Banjo Bolt that Detomaso used, but I haven't found; notice the step at the top, the top uses something like an M14 washer but the thread is M12 (or 3/8-24, I think, for all the brakes).
I ended up replacing the unions at the caliper and on the Master Cylinder and used more standard (3/8-24 or M12) bolts--Lee

Girling used brass/bronze banjos on most Pantera calipers. They clean up beautifully for reuse with a wire wheel. All the vendors carry them in stock, I think.

Thanks for all the helpful replys!

It's easy to find a bolt with proper thread size, the trouble arises around the 'shoulder' of the bolt (smooth area between the threads and head). The shoulder is too small for the banjo and it sits much too lose in the banjo to form a seal. I am visiting the brake line guy tomorrow to see if he can use a smaller (8mm?) banjo on the end of the line.

Thanks again

Ryan, this is why I just changed the union--ie. replaced the mate of the special shouldered banjo bolts I could not find...Those unions are relatively easy to find, with the exception of the ones I needed for the master cylinder (when adapting the reservoirs with 4.5mm line to the master cylinders, I finally found 4.5mm barb inlet banjo unions at Superformance.com.uk, that worked with the replacement Master Cylinder (supplied for Fiat Dino...more available banjos are going to have 5.5mm barbs). At the other end---Getting replacement 10mm or 3/8 unions for the calipers that screw right into the standard (AN-3?) brake hoses was easier...though I think I used a coupling as both the brake lines I got and the unions were both male ends)--Lee

Just removed my original factory hoses. On either side of the banjo was a "loc o" seal. Not sure what the auto world calls it but it's a serrated washer with a rubber insert that seals. Also have seen copper crush walkers used to seal the bolt to banjo area. You have to have a seal there.

Hi everyone, thanks for the discussion...sorry slow to chime in! To Ryan's original post - - if you're dealing with the rear Mangusta calipers (and they are the aluminum Girling type), banjo bolts from the FRONT caliper of a Pantera are identical. They have the required 11mm step or boss under the head, and are threaded 3/8-24. (see pic)

If you instead have iron rear calipers, they PROBABLY accommodate 3/8-24 banjo bolts but you'ld need to check to be sure.

As for Pantera REAR calipers, they use slightly larger (M10x1.25mmm) banjo bolts, so no useful spares there.

I don't THINK any front Mangusta calipers use banjos or need banjo bolts - whether iron or aluminum. At least there are none on my car, which has iron fronts....brake hoses screw directly into the calipers, a copper ring does the sealing. Looks like aluminum fronts are generally configured the same, so I assume no banjos for them either?

Nate, I can confirm that my Girling iron 12/3 rear calipers (used probably starting around the time '1076 was made, as I can tell) use the 3/8-24 banjo--Lee

Btw, as I can tell the banjos are part 1333A...Wilkinson shows them, however the picture they have online is just a standard bolt (though the description and $8 price give me enough hope to order and find out...! Thanks! Lee

Mangusta brakes are a crapshoot as far as what's OEM. Many Gooses had aluminum 2-piston Girlings front and back (same as 427 Cobras & priced accordingly), but not all. Steve Liebenow's "Blue Goose" had iron 3-piston Girlings on small 9-1/2" OD rear rotors, and I've heard of others being OEM. Get out the tape measure & camera before ordering parts.

Hi Lee, $8 for the right part would be great!! If it's a website glitch, however, vendors MUST have used ones from all the Pantera caliper conversions done...since those early days of Wilwoods...
