1972 Charger SE brakes

[salty_eye9692]

EDIT : I FOUND IT!!!! So based on comments apparently my car has the later 73 spindles. And I did order 73 challenger rotors. For some reason the challenger seal is too big to fit the spindle. So I found that the seal is a precision part number: 450076which has the outter ring 2.690 and the seal lip of 1.750. So I guess the answer is that the car was already converted.



I'm 26, been working on my first Mopar (1972 charger SE) for 8 years (takes a long time while learning and being super broke lol) got the front suspension together finally, after all new bushings, welding plates to the lower control arms, and new torsion bars etc. I have the new calipers and rotors ready to go; new races and bearings, used an "auto packer" to put grease in and filled the rotor cavity with grease to keep it from melting out of the bearings. I go to install the oil seal brand new from Timken. On both rotors the seal isn't a press fit inside the rotor bore. but it does slide onto the spindle and ride like it's supposed to. secondly there is no dust cap for the spindle nut ant lock for the front rotors. Thirdly I don't know think the brake hoses up front are the correct length. factory slide pin style calipers. car was originally a 318-slapstick car the rotors are a hair under 11 inches, so I think they are the 10.87 rotors. the oil seal I have is 1.75 by 2.375. inside bore for the dust cap is 1.790. Also, I have ZERO idea how the brake line routing goes since I bought the car as a decent rolling chassis. so, any pictures of the brake hose routing and brake line routing as well as the plumbing for the brake distribution would be VERY appreciated

TLDR What are the correct oil seals, dust cap, and front brake hoses for my car? And I need pictures of brake line routing and plumbing.

First thing I can tell you is that you do not want the hubs filled with grease. Pack the bearings with grease and coat the inside of the hubs with grease and that's enough. Too much will push out with normal heat and expansion. The auto parts store should be able to help with the correct seals and dust caps. Have you checked on Rock Auto?
Someone else will probably chime in with hose info.
Good luck with your project and have fun with the build! My current project has been ongoing since 2009.

I got my parts off rock auto and nothing seems to be fitting correctly.. so im gonna try oriellys tomorrow

72 is one year only, as is 71.

73 standardized until the end.

72 is a 2 piece rotor/hub with a different bearing than 73 and up.

There is a conversion collar to allow 73 and up rotors on 71/72 spindles.

Not sure about the seal, but makes sense.

AFAIK, 72 rotors are not available except NO$.

As noted above, the first thing you need to know is what brakes you have. Are they original, or a 73 up conversion, or something else?

How would I go about finding out? If I remember correctly I think they are like a challenger rotor or something? With slide pin calipers

How would I go about knowing that? Ive got the slide pin style calipers. Rotors im not sure. And id have to see what bearings im running.

Pin type calipers are correct for 72. Pics of what you have would really help otherwise we are guessing.

If the spindle is 1.375" at the inner bearing surface then you need 73 and up rotors. The earlier spindles are 1.25" at the inner bearing spot. Measure that diameter and see what you have. As above, pictures would help.

Thank you! I think they are 73 and up then. I have challenger rotors and slide pin calipers. I unfortunately cant get photos as im building her from a storage unit. After work in the dark ill try to get more. The bearings i have match the spindle cause I just got the same part number that was on the old ones. And put new races in. The seal i found that will work is a precision 450076
