M38A1 CDN 2 brake cylinder

Gilles: If those don't match then you may possibly have Cdn3 axles and brakes. As well, someone may have installed an upgrade on your brake system.

Can you provide a photo of your brakes?

A sure sign that you have a Cdn 3 axle is that there is no little hub cap on the back axle.....the Cdn3 uses a one piece axle shaft. Also, if you measure the brake drums, the older brakes are 9", and the Cdn3 is 10" x 2" wide internally, and have the wheel type adjusters on the bottom. Another give-away is that the steel line doesn't go straight into the cylinder, but at an angle.

If your brakes are the Cdn3 style, then the cylinders are the same as used on CJ5s of the same year with 10x2 brakes. Front cylinders will be WC37231 and WC37230. Rear cylinders were a WC37089 and 37090 if I remember right. I'm heading out to the shop tonight and I'll confirm. Seems to me on the military models, of those 4 numbers one of them is used twice and one is not used.

Since you are from the rustbelt area of Canada, you are likely gong to want to order the little S lines for the front wheel cylinders. They usually twist themselves apart and are available new.
