  1. Hello All, So I'm new here but have been lurking and finding good info here since I picked up my first Comanche in Aug 2017, finally got round to creating a profile... I have some questions about the Comanche braking system, I've been reading posts on this forum on this topic as I'm getting ready to lift and axle swap to make sure I'm covering my bases and this one got my attention: https://comancheclub.com/topic/40762-mj-brake-proportioning-valve/ There is a good picture of the MJ distribution block cut in half in the linked thread: My question is why is there no metering valve associated with the front brake circuit? Am I missing something? Is it separate from the distribution block on each front brake line? For a Disk/Drum braking systems I was under the impression that it was important to have a metering valve on the front brake circuit so that the line pressure to the front is delayed such that the rear drums have a chance to apply first since the drum shoes are not in contact with the drum, whereas, the front caliper pads are in contact with the front disk and apply almost instantly when the brake pedal is actuated. A couple YouTubes on this: https://www.youtube.com/watch?v=qzUk8W1-2pw https://www.youtube.com/watch?v=tUEsxZGuMk4 My second question is related to a statement that 1stDeuce made regarding Wilwood adjustable pressure regulators: "The Wilwood adjustable pressure regulator that has only one inlet and outlet is often referred to as a prop valve, but it is NOT. It only functions to limit pressure to an adjustable set point, meaning it'll allow full pressure up to a certain point, then limit it to that pressure no matter how high input pressure goes." I have not been able to find information to support this just doing random Google searches today - Anyone have some insight on what the pressure curve actually looks like for a single inlet/single outlet style aftermarket proportioning valve such as the Wilwood? I was considering using one of these aftermarket proportioning valves along with the LSV delete procedure outlined in the link below to clean up the braking system a bit and have the valving in place for a rear disk swap later on (which would then likely negate the need {or maybe just my perceived need} for a metering valve on the front brake system): https://comancheclub.com/topic/53274-mj-load-sensing-valve-delete-procedure/ However, if the Wilwood single in/out "proportioning valve" is really a pressure regulator that allows full pressure up to a setpoint then flatlines the pressure regardless of the input pressure after that, seems like you'd be leaving some stopping power under-utilized as opposed to a proportioning valve that just affects the slope of the pressure rise curve after the "knee point" or adjustable setpoint. In the interim, my thought is to maybe try using a combination valve off an 80's K-series pickup as I believe I can find one that will have the rear proportioning valve, front metering valve and brake light switch all in one unit and swap that into the Comanche while it is in the disk/drum version and then keep the Comanche distribution block to be used later with the disk/disk, adjustable proportioning valve scenario when I get that project lined up. Thoughts? Also, 1stDeuce suggested a Jegs part as an alternative to a Wilwood proportioning valve: http://www.jegs.com/i/JEGS+Performance+Products/555/63025/10002/-1 However, I didn't see any description of a metering valve being part of that assembly so maybe a good option for a disk/disk setup but maybe not a disk/drum setup due to the lack of the metering valve??? That's all for my first post. Any help would be appreciated.
