Front brake conversion....drum to disk question

[zeronetzero]

I have 4 wheel manual drum brakes and converted the fronts to power disk using the following....

12" Drilled & Slotted Rotors, 5x4.5" Bolt Pattern
BLACK POWDER COATED CALIPERS, Large Single Piston Mopar Slider Type
7/16 Stainless Steel Braided Brake Hoses
Backing Plates
Stock Height Spindles
Bearings, Seals, Dust Caps
Spindle Nuts, Spindle Washers and all Hardware.
8" Dual Black Powder Coated Power Brake Booster
Mopar Booster Bracket, Black Powder Coated
Wilwood Styled Black Tandem Oval Master Cylinder
Proportioning Valve Kit, Left Mount

I am experiencing excellent stopping however the car seems to pull to the left (front) once the brakes are applied.

The proportioning valve was not installed....could this be the cause ?

Thank you for the help

Sounds like there may be some air in the right front line/caliper. I would try bleeding them.

Bingo!

Something else occurred to me. Unlikely(!), but if the right caliper is at all hanging up that could also cause it. Probably not with a new install, but not unheard of if just pads are installed on old calipers that may have corrosion holding the piston out a little. GOOD luck!

What brand and where did u get them

Don't you have to use the proportioning valve and with that the metering valve for disk brakes, other wise you will not get correct pressure, especially with a power booster.
