photo or diagram how to reroute the right front brake line

CRAIGXLH1 · Aug 12, 2018

Hi do anybody have have photos or diagrams how to reroute the right front brake line on the firewall. On a b-body so I can go to the drags race. I have a 69 GTX last time at races a few years ago they told me that had to reroute my right front brakes line. thank you

Back in the day we had to run the right side line in front of the engine. Not on the firewall but that was 100 yrs ago talk to dvw,malex Mike Gaines and nss these guys have the rules down and could give you insight. Racers hangout good luck

I saw this on a Sox&Martin car.They ran the brake line from the master to the front,around the bottom of the rad support and over to the right side .

I did it that way and ran rear out side frame rail. Used insulated clips to hold them. Wait for the race guys though.

i meant the right front brake line away from the firewall stock location and away from the rear of engine sorry for the mix up thank you

You run the brake line forward along right frame rail then down under the radiator. Run along left frame rail to junction block. I did mine with no radiator in the car, didn't want run it on bottom of radiator support . Used insulated clips to hold it in place.

Just curious, Why does the brakeline need to be rerouted?

Fran Blacker · Sep 2, 2018

It was to move brake lines away from possible clutch/flywheel explosions cutting brake lines.
Don't know what classes it applied to.

2018 NHRA general rules on brakes -
"General
Regulations
Section 21, page 17
General Regulations
Brake lines must be steel,steel braided, or DOT-approved flexible and routed outside the
framerail, or enclosed in a 16-inch length of 1/8-inch minimumwall thickness steel tubing securely mounted where line(s) pass the flywheel bellhousing area and not routed in the driveline tunnel."

Since you have to redo the line on the firewall just to enclose it in the tubing, you might as well reroute it.

Not to get off topic but what purpose /benefit is it to have a manual prop valve feeding into a distribution block (auto prop)????
Thanks

Good question Mike. I'm really not sure why. It's just a distribution block so I'm guessing it made the routing to the rear easier or cleaner.

Fran Blacker · Sep 11, 2018

The only reason I can think of not to do it that way is if you have a brake warning light hooked up. The distribution block has a pressure differential switch that would light up, meaning there is a brake problem. Think this is the reason?

She's not utilizing a warning light so I just don't know for sure. I'm going to ask because now I'm curious.

I'm no brake wizard and am still learning my way around the black magic that makes systems work.
Its hard to see the block in the pic but it sure looks like a factory type prop valve...are you sure it's just a distribution block???? Or am I misunderstanding when you say distribution block???
Thanks Shorthorse/Fran!

Fran Blacker · Sep 12, 2018

Looks like Shorthorse used d block for front brakes only.

Does the master cylinder need to be moved?

Fran Blacker · Sep 12, 2018
