Metering/ Proportioning Valve tuturial
I did my disc swap today and also changed my proportioning valve. The Mitsubishi Part Number is MB699551. This fits an 8G with a 3.0 V6 w/o ABS.
Tools needed:
10mm line wrench
12mm socket and ratchet
PB Blaster
The valve is located on the right firewall, behind the alternator on an I4

Spray all connections with PB this will help ease the loosening and help prevent damage to your brake lines.
Using the line wrench disconnect all six lines from the valve body. Make sure you leave the valve connected to the firewall. Again this reduces stress on the other brake lines.

After all six lines are disconnected you can remove the valve body from the firewall.

Put your replacement valve on the firewall and hand tighten the bolt fastening it to the firewall. You want to leave a little bit of motion in the valve body till the lines are all reconnected to help prevent the threads from stripping. Once you get the threads on all six lines started (make sure they are installed in the same location) you can tighten the fastening bolt the rest of the way. After the body is secure you can finish tightening your lines.

After you install the valve you must bleed the brake system (ALL FOUR WHEELS) to ensure proper performance of the braking system.
I hope this helps any of you who are undertaking this task. If anyone has questions feel free to PM me.
