Master cyl/prop valve & line lock

[theman440]

I'm converting my drag car to rear disc and I am trying do decide how I want to set up the components, specifically where to mount the prop valve & line loc . . .together on or near the master cyl?, down low on inner fender where stock prop valve is . . . ETC. I'd love to see how some other racers have done it. Pictures would be nice too.

Thanks!

Ditch the disc brakes on the rear on a drag race car. Keep the 11" drum brakes.

The Quick Performance rear axle assembly had a disc brake option, so on my wife's GTO we went from stock 4 wheel power drum to Wilwood master cylinder, a new 8" booster, prop valve, line lock, 11" rear discs and 12.19" fronts.
I really like where the shop installed the prop valve and line lock.

The new line lock is mounted on the inner fender.
The old one that was on the car wasn't working and was found under the fender near the wheel.

Here's something I went with, mines in black.

Here's it installed without the prop valve.

This is similar to how mine is set up now.

Nice clean set up, question - did you drill the holes to mount the prop valve?

Here’s mine. Mounted to a bracket under the m/c proportioning valve in front, line lock in back.

Thanks for the input gang - I've decided to go this route with line loc-and mount the prop valve down low on the inner fender below the master.
