[5al9nee]

slam for all, Good Day!
As alot of passionate builders we throw our self
into somthing new ,

so one of projects want ages to be all done
now i'm into reline the brakes.

manual master / 6pistons caliper front 4pistons caliper rear/ 3/16 stainless steel hard line all around / many L banding
(frame shape) / one tee at axle.
with big wheels and LS motor.

i think the lines kind of small?
still never try the truck,
where the mistake on that setup? no one like to push a rock padel brake isnt?
