Drum Brake Cylinder replacement -Autozone parts have issues

[MrJ]

FYI: I had some major issues when replacing the brake cylinders with Autozone parts. This applies to both sides/parts.

The Part Number: 33655 (driver side)
Part Number: 33656 (pass side)

If you try and use a regular brake line nut it will bottom out. I had this issue on the drivers side but didn't keep the old cylinders to find out what the deal was. I thought the nuts were special. No, Autozone parts are not correct. 1/16ish off makes a difference. I used a special spacer I bought from a place that makes hoses/lines. I cut the spacer down to just the big part. (picture doesn't show that..)

Also, the 3 bolts that hold the cylinder on are 5/8.. Good luck finding those!! I used Grade 8 3/4 with washers to get the correct length.. FUN!!



Maybe Napa would be better, but it seems all the auto parts stores carry the same part in relation to a 76 P30. Donno..

MrJ,

I bought all of my rear brake parts for my 74 Argosy from Rockauto and fortunately had no issues like you experienced.

Sadly it's getting harder and harder to find good quality replacement parts.

AZ... well, a lot of parts are 'recycled'... and not by true 'professionals'... sometimes to 'minimum acceptable level'... by experience, not opinion...

I go to a local 'old time' part supplier and buy 'new'.. especially on important items like 'brakes'...

AZ also bumps up price for items like windshield wipers, etc.. that are made by others only as 'new'.. in the 'bubble packaging'..

One example.. I bought a "grade 8" bolt from AZ for my HD... as I was torquing, the bolt head sheared off.. on inspection there was a "void" between the shank and head.. It was doomed to fail... had it failed when I was 'running' the HD, it would have been very, very ugly..
