Tundra brake pedal goes to the floor!

My break was pretty ok until I needed my rear drum and shoes replaced. Ever since my brake gets gradually worsen even my E brake goes to the floor without any effect.

Front pads are relatively new. Fluid level is also good and not that old.

Can't figure out the problem. Any input appreciated.

Yep, the parking brake not working is the give away. Its either loose, stuck, or broken somewhere, disabling the automatic adjustment of the rear brakes, which are very sensitive to being out of adjustment. Because the parking brake and the hydraulic brakes share the same shoes on our trucks, if those shoes are not perfectly adjusted, your entire braking system will suck and feel soft. The factory spec is for 1/100th of an inch MAXIMUM clearance between the shoes and the drums so as you see, there isn't much room for error.

You can adjust them manually if you have to, but they will come out of adjustment again unless you fix the parking brake and get the automatic adjustment working again.

See the above link.

 

That stupid mechanic who replaced the shoe and drum didn't adjusted properly, I might have to take it to Toyota because it's raining here all week and I need to drive it. it is getting scary to drive this thing when the brake goes to the floor.

 

Well, keep in mind, the only procedure in the factory service manual for adjusting the brakes is to repeatedly apply the parking brake. If your parking brake and auto adjuster system is working right, nothing else is needed to adjust the rear brakes.

The mechanic may not have been exactly stupid, they may just have followed the book, not realizing that your parking brake is broken.
