Crown Vic Question... What is this part?

[Trouper]

As you can see in the photo, there is a thick peice of aluminum attached to the side of the master cylindar (1999 Crown Victoria), inline with one of the brake lines. Since I added my K&N FIPK, I have been having some vibration in the brake pedal, and found that it contacts the brake line behind this "aluminum block", causing the vibration. If the "aluminum block" was removed/moved, it would solve my problem. A buddy of mine said it was a "proportioning valve" and necessary. I just want to remove it or move it down some for clearance. If it's necessary, would it hurt anything to take it off, put in a 90 degree elbow brake line and re-attach it, moving it down some? Suggestions or comments?

I believe so anyway. That is a proportioning valve to hold off the rear brakes and give greater braking potential to the fronts. Is there any way you can adjust the route of the air intake tube? That would be a better alternative.

Good Luck,

I wouldn't fool with that valve. Thy to make an adjustment of the K&N filter.

I agree. Make your adjustments at the K&N, I wouldn't fool around with the brakes.

Which kit did you get? The Gen 1 or Gen 2 kit? I have the Gen 2 kit and the tube was flattened at that position so it clears that brake line.

Nevermind, I just looked at pictures of mine and it has a different setup. The long tube it to the rear of the master cylinder.

[Trouper]

I have the GEN2 kit, but it still makes contact no matter how I fiddle with it. I was told that putting in a 45 degree fitting would be fine to move it down a touch, but that will be the last resort. Maybe a spacer under the intake plenum would help?

Trouper: I ran into the SAME EXACT problems planning out air tube installs. K&N assured me the Gen 2 FIPK would work. I asked them if it would work with the proportioning valve there and they said yes. You can see how accurate they were :(

Let me take a wild guess here: Do you have ABS? Do you also have traction control?

My 00 HPP has ABS and Trac Ctrl, and it has that valve. The later models are designed a bit differently so the valves aren't necessarily there.

[Trouper]

Thats a check on both, ABS and TC. I am going to fiddle with the FIPK for a bit, then if I can't get it right, just add some rubber inbetween it and the lines. Thanks to all that replied!

None of my three Marauders (2 300As, 1 300B) have that device installed on the forward line, if it's a device at all. A smaller, but similar device appears on the rear (meaning closer to the firewall) brake line coming out of the Master cylinder.

I doubt this is a proportioning valve, both lines lead to a distribution block that rests on the frame, across from the engine mounted/belt driven power steering pump. All proportioning and ABS functions are controlled from this distribution block. Two lines in from the Master cylinder, four lines out, one to each wheel.

What this do-hicky is, I don't know. My 2003 Helms book doesn't show it in any diagrams. It's not ABS related, or, brake fluid level indicator related. Neither is it related to the auto park brake release on the 300As, because I know where all that is controlled from.

Considering it's OD on my cars, seems to be just a one inch extension for the brake line attached to it. Methinks maybe a fix for an NVH issue?

Most of our brake lines solid and fixed, maybe this do-hicky only meant to put some space between a brake line and something it conflicted with, maybe the frame? The Marauders are different frames from the CVs prior to 2003, so, maybe? Dunno...Got me stumped now...BTSOOM!

Now here's a suggestion. Just an idea.

Use a heat gun to heat the offending area (dont melt/burn the damn plastic), use a piece of conduit or PVC pipe or wifes rollign pin, and press/deform the area slightly to clear the hingus thats hanging off the MC.

Just an idea.

Ummm...If a heat gun can give you some relief here, what will engine bay temps lead to?

[BK_GrandMarquis]

I just looked through a Ford Workshop manual and it didn't show that part that you have on your car Trouper. Go figure.:dunno:

PHP Brake Booster Spacer, Duh!

You know, like what the intake spacer does for the upper intake...

:D

it is the brake pressure control valve:
It is in this location for 96-02 IIRC ABS panthers equipped with ETA/ Traction Control
it's purpose is to control the amount of pressure out of the m/c's secondary circuit, which supplies the rear brakes.

[metroplex]

Correct, it's not on 03-up Marauders.
It's only for 98-02 Panthers with BOTH ABS and Trac Ctrl.

[SergntMac]

I love it when the correct answer is found. Thanks, guys.

I brought this issue up on CVN awhile back but no one had found a solution. Liquid first ran into this problem when he used the 04 zip tube on his 99 HPP.

I still run the 04 zip tube but I've layered a bunch of stuff between the valve and the zip tube.

[Drock96Marquis]

The best soultion I could think of, short of trying to relocate the valve via a 90* elbow (as who knows what size the thread actually is) is to use a M/C from a 1995 or older panther equipped with both ABS and ETA (Electronic Traction Assist)

The valve is present on said models, however, it points downward vs out the side like 96-02s.......
of course you would need to attach new flex s/s sections, it will line up a little different and the current ones lack any slack to 'rig' it.
other than that I can't see an issue with using it. it looks near the same, cruise and brake level senors are present, larger primary line just as the 96+ have, and the mounting flange/bolt locations are the same...
