Brake pedal to the floor - still need help

[Paramedic]

Just came out of the garage and somehow I feel like it goes 5-10% less to the floor but here what the mechanics said:

1. High quality brake pads used at about 20% max
2. Brake oil system was bled although no previous sign of leakage
3. Rear cylinder in good condition

Any ideas??
thanks fellas

What year is your vehicle? I've read about brake boosters being bad, test involves getting into 4 low, going 10 mph, and then hitting the brakes hard, you should come to a stop quickly.

Rear brake adjustment. Pull up your E brake. Should take around 9 clicks. This will tell you your shoe to drum distance which directly affects pedal height.

I'm currently going through the same thing. here's my story.

-bought vehicle
-took off rear drum to see how the shoes looked, looked horrible so I put the drum back on and ordered up shoes from toyota but at this point now, when I hit the brake pedal, it felt like there was air in the line. I never opened up the system though.
- I go back in and replace shoes, wheel cylinders on both sides just for good measure, and replace the parking brake bell cranks on both sides because one had seized and then adjusted the shoes per FSM, go out and and do the whole reverse and brake thing... still feels like air in the system!!!
- Currently I'm questioning the brake lines, and wondering if on the flare there is a crack and maybe it happened after I went in the first time like I nicked the line or something with a tool. I'll keep you updated on what I do next.

Yea, check rear adjustment first. Sounds like there is still air in the lines, bleed it again? I know I had a 96 that was a bear to get bled, seemed to do with the ABS. It felt a lot better after I took it out in the snow and locked up the ABS a few times, pedal felt better afterwards.

rear drums do require replacing if the brake shoes wear un even . if the shoes wear at the top then the drum is NFG.

with rotors you can get away with wear on drums what happens is the brake pedal will travel more with worn drum.

most times this is also revealed when the park brake cables require adjusting to hold vehicle in place.

Sorry, but you really need to explain what that means, and what the truck was in the shop for. Otherwise it could be the phase of he moon.
