    DBMC09 is rated 4.7 out of 5 by 6.
    Rated 5 out of 5 by from DBMC09 master cylinder works great for 69 Camaro. Used this master cylinder on my 69 Camaro with a big block with front disc and rear shoe brakes and a metering block. Works great. The old MC was applying front disc when area temperature rose. This MC solved the problem.

    Rated 5 out of 5 by from Worked Great for my Manual Disc Drum Setup I was looking for the right MC to do a manual disc drum set up on my 65 C10, didn't want to do power because the cammed small block in the truck has a lack of vacuum and because its an old truck and I like to keep it a little old school as far as driving. Looked all over the internet with a lot of dead ends and no help. Wound up finding this and doing an online chat with Jegs, they recommended going ahead and getting it said it would work. They were definitely right because I have the truck back on the road thanks to their quick shipping methods and advice. I would recommend this part to anyone whether it be disc/drum or drum/drum Chevrolet applications where wanting to stay with their manual brakes. Don't listen to all the naysayers at the local parts stores saying they don't make the MC to do so, this is the one to use.

    Rated 4 out of 5 by from Works well after converting manual drums to disc Used the DBMC09 Master Cylinder on my 67 Camaro after doing a manual front drum brake conversion to manual disc brakes. Vehicle is a 12.20 bracket car. The only issue I have run into with this unit is after a few years of use, the brake fluid from the front reservoir starts running low while the rear reservoir starts over-flowing and leaks out from under the cap. I first thought maybe the fluid was moving from the front to the rear reservoir over time from dozens and dozens of launches at the track; but I now believe there must be some internal valving issue or something. I'm getting ready to purchase my third unit soon (April 2020) over about a 12 year span.... For the last couple years I had been just manually transferring fluid when it started over-flowing out of the over full rear reservoir and placing it back in the nearly empty front reservoir; sometimes putting a new cap and/or cap and rubber seal back on... (also tried using zip-ties to hold cap down tighter, but this didn't solve problem)

    Rated 4 out of 5 by from Works as advertised Direct replacement for a leaking MC on my 68' Chevelle with disc/drum brakes. Does not come with the master cylinder bleeding kit that is shown, just the MC and some stickers.

    I understand this also works with 4 x POWER Drum Breaks configuration (front and back drum breaks)?

    Asked by: wigoplus
    This is for use with a disc drum application. Here is a link to all of the master cylinders. http://www.jegs.com/p/Right-Stuff/Right-Stuff-Master-Cylinders/1556311/10002/-1

    I'm currently working on a 63 c10 with drum brakes all the way around, my original master cylinder was a single feed but was shot, I'm looking to convert to a dual and was wondering if this unit would work good for my application?!

    Asked by: Tdubs
    Yes, this would be a good choice to use.
