Soft brake pedal after new line and bleed

Last weekend a hard line broke on the front passenger on my truck.

I had the line replaced and bleed by a shop out of town, but the pedal was still soft.

so When I got back into town i brought to a toyota dealer to have them fix it, they've re-bleed everything, but its still soft toyota is saying that a new master cylinder might fix it.

looking for second option before I just start throwing parts at my problem.

 

Try going on a gravel or slippery dirt road and jamming on the brakes to activate the ABS system a half dozen times or so. See if that brings the pedal back up. It works for some "soft pedal" issues. No Charge either!

 

I'll try it either later today or tomorrow, thank you.
