Dual Reservoir Master Cylinder Conversion Kit for 41-71 Jeep
This kit is an important safety upgrade from a single reservoir braking system. The kit includes a dual reservoir master cylinder, mounting brackets and all required fasteners and instructions. This master cylinder kit is intended to install to your Jeep withouth cutting or grinding. You will need a 3/8″ drill bit, a double flare tool, or a buddy with a double flare tool to modify your existing brake lines. You will retain your factory original master cylinder bracket. Its as simple as it gets!!!
For vehicles with original 9″ drum brakes
Note: This kit is designed to work with the late CJ-2A, CJ-3A, CJ-3B, CJ-5 and CJ-6 with NO DRILLING. The MB, GPW & early early CJ-2A will require a later pedal shaft bracket (rivet style) to use this kit – our part number: 645086. The M38A1 will require drilling through the factory pedal shaft bracket.

NEW! New Dual Reservoir Master Cylinder Conversion Kit – Part#: 805223-CJDUAL
Q: I have a 1960 Willys L-226 utility truck will the master cylinder kit work on this model for the dual reservoir conversation. And do you carry a steering column shaft for this model also.
- A: Try part number: 805223-WODUAL for your Willys Truck. That will be the correct one.
Q: What’s your average ship time on this product?
- A: We typically try to ship same day.
Q: If my 1968 CJ-5 already has the dual reservoir master cylinder conversion but it’s time to replace the master cylinder which master cylinder should I use?
- A: It really depends on what master cylinder the previous owners used on it. In that year it could have had a stock dual res too…
Q: When installing, do I plumb the front brakes to the rear reservoir and the back brakes to the front?
- A: Yes that is correct.
Q: Can I use the front and rear brake line kits that Kaiser Willys sells and just build the frame brake lines? If so, what do you recommend for the frame lines. I would like to buy lines that are already flared since I don’t have a flaring tool.
- A: Yes that is correct. This will not affect the front or rear lines and our kits will work. Your local NAPA sells predetermined length pre-flared lines. You can easily make them off of that.
Q: I have a 1953 pickup with the reservoir on the firewall will this conversion kit work?
- A: That is unoriginal. I’m sure it could be made to work with some modification.
Q: Does this master cylinder works on a 1956 CJ-5?
- A: Yes that is correct. It goes for all the vehicles listed above.
Q: Do you sell the kit without the master cylinder? I have the master already.
- A: Please call us toll free. We probably can get the brackets by themselves.
Q: The frame mounted master cylinder is less than desirable on my 1944 Willys army Jeep. It is difficult to get to to add fluid and seems to fail often. Is there such a thing as a conversion kit for a dash mounted master cylinder combined with an uplift brake pedal?
- A: You should have an access cover on your floor board to add fluid to. It would be pretty hard to get a under dash to work for the Jeep.
Q: How do your stock lines hook up to the new master cylinder?
- A: No, you have to run new lines to it.
Q: Do I need an portion valve between the cylinder and lines or can I hook front brakes to the front and back brakes to the back of master cylinder and do you seal such a block or valve ?
- A: If you are running drum brakes front and rear then no you don’t need a prop valve.
Q: I have the brackets, what is the part # on just the master cylinder?
- A: Please call us toll free. We can special order it for you.
