55 Fargo Posted March 3, 2018 Report Posted March 3, 2018 This was posted on the HAMB 1936 Plymouth with odd ball disc brake conversion using no adapter plate. Anybody recognize the caliper, rotor and hub assembly... Quote
Robert Horne Posted March 4, 2018 Report Posted March 4, 2018 The Lincoln, Navigator look very similar......... Quote
Adam H P15 D30 Posted March 4, 2018 Report Posted March 4, 2018 Sure looks like Volvo. Popular swap on pre-war Fords years ago.... Adam Quote

Adam Thats what some of tbe HAMB guys think too. Looks like caliper is bolted right on and used hub and rotor over stock spindle. Quote
Robert Horne Posted March 4, 2018 Report Posted March 4, 2018 (edited) The Volvo rear disc is solid, & has a 108mm/4.25 inch bolt circle. Edited March 4, 2018 by Robert Horne Quote

Anybody recognize the caliper, rotor and hub assembly... The rotor hub section looks very deep. I thought about a setup on my 38, using an Explorer disc...Still use the original hub.... Quote
55 Fargo Posted March 4, 2018 Author Report Posted March 4, 2018 I m guessing to allow this setup too work together the hub and rotor are deep looking.. Quote
Robert Horne Posted March 11, 2018 Report Posted March 11, 2018 This setup seems to be a early Volvo, maybe a 88 or 89, caliper that has a mounting center bolt holes at about 3.5 inch. The Plymouth mounting holes are about 3 5/8 across the top, and about 5 5/16 from top to bottom. I believe he used the original top rear bolt hole, and drilled the bottom rear hole for the second mounting bolt for the caliper mounting.. The rotor may be an Explorer to get the 4.5 inch lug pattern.... 1 Quote
Adam H P15 D30 Posted March 12, 2018 Report Posted March 12, 2018 (edited) Volvo’s had solid front rotors with 5 on 4.5 bolt circle. Dad had that very setup on his 35 Ford in the late 80’s. Adam Edited March 12, 2018 by Adam H P15 D30 Quote

Found this link: 122 & 1800 models up to 1969 use a bolt pattern of 5-on 4.5 https://www.ipdusa.com/blogs/280/all-about-wheels-for-rear-wheel-drive-volvo-models Its interesting Robert, you looking at doin it? If you do please post it. Quote
MackTheFinger Posted March 12, 2018 Report Posted March 12, 2018 (edited) Had a PV 544 in the early '70s that had 5x4.5 bolt pattern wheels.. One of my favorite cars.. Drum brakes, though.. Maybe the P1800 or 122 had discs?? Edited March 12, 2018 by MackTheFinger adding content Quote

If you do please post it. Thanks for the link. I have not been looking into old enough Volvos for the 4 4/5 bolt pattern. I had researched a few years ago on doing disc brakes, with Explorer rotors, and some type of bracket for the caliper. The Volvo setup would be the way to go, it seems. I will do more research into this... My stock brakes have worked ok, until the last time I drove my 38, and front brakes failed, due to loss of fluid. I still had rear brakes, thanks to the Bronco MC setup.... Quote
Adam H P15 D30 Posted March 12, 2018 Report Posted March 12, 2018 Checked with dad and though his memory isn’t what it used to be he told me he used 70’s Volvo 122s brakes. Adam Quote
55 Fargo Posted March 12, 2018 Author Report Posted March 12, 2018 Are you guys sure? Rock Auto sells the calipres cheap What about the cylindrical casting the hose attaches too. I dont see that on 1988 volvo calipres Quote
55 Fargo Posted March 12, 2018 Author Report Posted March 12, 2018 Could this be a good low cost conversion option? Quote
Adam H P15 D30 Posted March 12, 2018 Report Posted March 12, 2018 55, if your asking me, better double check on the model of Volvo. Not that I doubt my dad’s memory but he’s no spring chicken. Adam 1 Quote
Robert Horne Posted March 12, 2018 Report Posted March 12, 2018 In the first post photo, the rotor seemed very high. This photo of a 1968 rotor, Volvo 1800S, is for the rear, 4 1/2 bolt circle, seems higher than front rotors. I seen rotor listings of 67 to 74 140 Volvos that suppose to fit 1800S Volvo, but had a 4.25 circle. Quote

I get conflicting info from different sellers. Going by the first posts photos, my best guess so far, is the rear rotor from a 68 1800s, and the caliper from the 1988 Volvo 240..... 1 Quote
Adam H P15 D30 Posted March 12, 2018 Report Posted March 12, 2018 (edited) So, talking to dad it seemed it was a hub and rotor assembly with bearings, races etc. He bought a 3/16 spacer from JC Whitney that went against the inner bearing. Big difference from what the original poster showed, is he did have to make a plate for the caliper to bolt to the spindle. It wasn’t cast into the caliper. I showed him the picture of the caliper on this thread and he thinks it MIGHT be early mustang but that’s a guess. Early mustang was a popular conversion in the late 70’s as he remembers. This was 30 years ago on a Ford spindle. I do remember flying to Kansas from California as a kid to pick up the parts. Hope this helps, Adam Edited March 12, 2018 by Adam H P15 D30 Quote
Adam H P15 D30 Posted March 12, 2018 Report Posted March 12, 2018 (edited) Oh and he said the Volvo calipers were 2 piston not 4 but the rotors are spot on for Volvo. Edited March 12, 2018 by Adam H P15 D30 Quote
55 Fargo Posted March 13, 2018 Author Report Posted March 13, 2018 Interesting, but looking at early Mustang and Volvos, this caliper still looks different than those. At any rate, hope someone can positively Identify the entire set-up, could end up being a nice alternative for a disc swap... Quote
Robert Horne Posted March 13, 2018 Report Posted March 13, 2018 Here is a couple of photos of the 88 and 89 Volvo caliper. The closest to the original photo so far.... Quote
