problem with brakes 1987 toyota

[phreakelady]

I have replaced all brake lines and bled them out. Seemed like they would be fine. But when I started the truck the went out again. Any ideas?

We need more info than "went out". Can you be more specific?

Maybe a more detailed description of your overall issue?

Just bad brakes or just since the line replacement?

"Started the truck" - as in rolling and applying the brakes or the engine running and then fail?

what else did you replace, and why did you replace all the brake lines? where they leaking?

Did you bleed them from the back first then work up front.
Does it have a proportioning valve they can be tricky to bleed at times.
