mikeyz123 Posted January 23, 2019 Share Posted January 23, 2019 Hey guys so i replaced the wheel cylinder on my rear right wheel and everytime i put everything together the pins on the wheel cylinder that push the brake shoes are crooked. Any advice Link to comment Share on other sites More sharing options...
TerryB Posted January 23, 2019 Share Posted January 23, 2019 (edited) I think your bottom shoe adjusters need to be re-aligned to the same starting point. Note how the left one is rotated more than the right. They move the shoes closer to the drum to compensate for wear. Your shop manual should explain how to align them. I think they have arrows stamped in them to set their starting point. Edited January 23, 2019 by TerryB (see edit history) Link to comment Share on other sites More sharing options...
61polara Posted January 24, 2019 Share Posted January 24, 2019 Quote The arrows on the bottom should point directly to each other before you begin to adjust them. I can't tell the direction on the one on the left. That may be your problem. Also, why does everything look wet, like it's soaked in brake fluid? Use brake cleaner to clean every thing up. If brake fluid got on the linings you need to replace the shoes, 1 Link to comment Share on other sites More sharing options...
mikeyz123 Posted January 28, 2019 Author Share Posted January 28, 2019 thats the problem, when I align the arrows with the wheel cylinder the drum won’t go all, but when i turn them away the drum will go on Link to comment Share on other sites More sharing options...
TerryB Posted January 28, 2019 Share Posted January 28, 2019 Take a photo with them aligned and post it. Link to comment Share on other sites More sharing options...
TerryB Posted January 28, 2019 Share Posted January 28, 2019 Check the new wheel cyl against the old one. There have been reported issues with pin length differences on newer wheel cylinders. 1 Link to comment Share on other sites More sharing options...
Spinneyhill Posted January 29, 2019 Share Posted January 29, 2019 The pins seem to be mounted against a different place on the shoes. If so, why is that? Is there a groove on each shoe for the pins to mount in? If they are different, are the shoes swapped front to back? The left shoe in the photo appears to be lower than the right shoe in the photo. I would attempt to set the bottom anchors so both shoes are at the same level vertically and as close together as they can be. Link to comment Share on other sites More sharing options...
c49er Posted January 30, 2019 Share Posted January 30, 2019 (edited) The replacement Lockheed style cylinders now mostly all made in China are made incorrectly position wise and with all different types of piston depths and piston rubber cups.. This can cause the need for a shorter push rod. Also too thick of shoe lining can be an issue on these old Mopars...... .185" max thickness on lining...... and linings need to be arc'ed to fit each drum... A lot of things people need to know when working on these old Mopars and to do them right need some special tools or drive em till the shoes wear in to the drum shape and keep adjusting brakes till finally seated in 100% then they are awesome brakes and work extremely well. Asbestos linings are the best for service but I will not go there. Some pics of all these issues...

He might be talking about these retainer springs used on the heavy chassis Chrysler brakes... eight cylinder and wagon 12" brakes ...they are similar to bendix brakes... There is a pin, rubber inner insulator, steel tube sleeve, spring and retainer cap. 1 Link to comment Share on other sites More sharing options...
