Merle Coggins Posted January 15, 2021 Report Share Posted January 15, 2021 Remove that nut on the back side of the eccentric pin, and remove the pin. This retains the cylinder. Quote Link to comment Share on other sites More sharing options...
allanp Posted January 15, 2021 Author Report Share Posted January 15, 2021 Of course everything is rusted and seized. how do you hold that pin from turning? the back little tab? Quote Link to comment Share on other sites More sharing options...
JBNeal Posted January 15, 2021 Report Share Posted January 15, 2021 (edited) It might be easier to remove the shoe to get a pipe wrench on the cam end of the pin then work the nut back and forth to break it free, using plenty of Marvel Mystery Oil or equivalent penetrating lubricant is highly recommended. Take your time and the parts should be able to wiggle apart without chewing the pin head or breaking off the alignment tab. additional information - horseshoe clip detail additional information - horseshoe clip removal Edited January 19, 2021 by JBNeal revised information Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted January 16, 2021 Report Share Posted January 16, 2021 Isn’t there flats on the back end of the pins that allow you to hold it with a wrench to loosen the nut? Quote Link to comment Share on other sites More sharing options...
JBNeal Posted January 16, 2021 Report Share Posted January 16, 2021 (edited) Loosening, yes...but if that nut is frozen, there's risk of damage to those flats. Better to clamp the hex nut in a bench vise after removing the backing plate so that pin is vertical, douse the threads with penetrant, and use a pipe wrench to work the pin back and forth to break that nut free...I found out the hard way that even putting a large crescent wrench on them flats doesn't guarantee that they won't get boogered up when they twist to the point that the crescent wrench slips off and won't stay on anymore.

allanp Posted January 18, 2021 Author Report Share Posted January 18, 2021 ya its frozen. the pin will push through the shoe and backing plate from the brake side, out toward the nut? have all the springs off and seems tight and like that nut needs to come off so the pin comes out the brake side. ??

Yes the pin comes out the brake side. Loosen nut and drive from backing plate side out to the brake side. 1 Quote Link to comment Share on other sites More sharing options...
dcotant Posted January 18, 2021 Report Share Posted January 18, 2021 (edited) You can see the pin is smaller diameter in the part that goes through backing plate than the part that goes through shoes.

allanp Posted January 27, 2021 Author Report Share Posted January 27, 2021 Thanks guys. next question. Anyone know common supplier part numbers for wheel cylinders. Fronts and the half duals on rear. I know the classic parts suppliers have them but I’m looking for dorman, ac delco, raybestos part numbers Quote Link to comment Share on other sites More sharing options...
