The Stovebolt Site Forums The Parking Lot Big Bolts Hydraulic braking - replace everything: 1967 C50 dump truck

NEW TO THE GROUP

I've got a 1967 C50 and it has an all hydraulic braking system and we're looking to replace everything in the braking system including both front wheel seals and rear wheel seals.

Is there a 1 stop shop for everything you would recommend?

TIA
Brian

I like to order stuff from Rock Auto. I hate going to stores if I don't have to.

slimedcj - 1st off Welcome to Stovebolt! Since your asking for help on your 1967 C50, I've move your post to our Big Bolts forum as that the best place for further help and conversation on your truck. Others should be along soon to offer further help and suggestions.

My first stop would be to your local NAPA -- especially if they cater to customers with commercial vehicles. They probably won't have that vehicle in their computer but a good counterman/woman should be able to pull out the books and find what you need.

Hy slimedcj and guys, welcome, unfortunately the larger trucks of this era can have many different brake components, single systems, dual systems, different bore master cylinders and wheel cylinders, firewall mounted boosters and under truck boosters. Please take some pictures of the components you have and post them here, it will help us to determine what you have. Brakes on the larger trucks vary depending on the trucks GVW among other things.

It's a single system , firewall mounted booster , dual wheel cylinders

I didn't take things apart yet but I'll get some pictures tonight. Thank You all for the reply's

Hi slimedcj, welcome to the forum. I was able to find rebuild kits for all 6 wheel cylinders and the master cylinder, I also rebuilt the Hydrovac with a nice kit. The wheel cylinders will have a casting number on them, that is the info you need for kits. I replaced all hard lines with copper-nickel and all hoses, brakes have been great for 4+ years with no issues. My truck is 10 years older than yours but the wheel brake set-up is probably very similar.

There is no one stop shop but I spent several weeks/months gathering these part numbers and finding modern ones that are still produced.

The following is for a 1967 c50 with 5000lb front axle, 15,000lb 2 speed vacuum shifted rear axle, and midland vacuum brake booster.
