Brake issues

2005 sequoia.
Brake line failed at multiple connections for driver side front and rear brakes. The reservoir was completely empty, it had been sitting a couple days. I completely replace those hoses and brake lines to the abs module. Filled up the reservoir and bled the brakes. No leaks and had good pressure on the pedal. Started her up and the pedal went to the floor and i noticed red brake light on dash. When i bled the passenger side i did notice the fluid didnt come out as strong. Drivers side was good. Forgive me on the rambling i am tired and frustrated. Thanks in advance for any ideas you throw my way.

 

Are you bleeding manually, pressure bleeder, or vacuum bleeder? Might double check the passenger side hoses or lines that were replaced for leaks again.

If the bleed job was solid, it’s possible the master cylinder has failed. The pedal going to the floor isn’t good.

There may be a distribution block on the rear, where the L and R lines split. There may be a bleeder valve on that block.

 

Manually bled them. No leaks tha i saw. Pedal was firm when bleeding was done. After starting her up pedal went to floor went up and down driveway still pedal to floor. Shut her down checked my work and all other brake lines all looked good checked the reservoir and no fluid loss.

 

Not sure on our recent tundras and sequoias but sometimes there are procedures that have to bleed the abs motor itself too. I’m not sure if we do on ours but on other makes you sometimes need a scan tool or a dealer. Just throwing it out there in case it helps looking into.

 

From what i could see there isnt any brake proportioner on the rear anywhere. I traced the back brake lines from rear tires to abs module. Im wondering why the passenger side front and back calipers just dribbled but the drivers side lines which i replaced all had strong burps then strong streams of brake fluid.

I bled the master cylinder and then bled the calipers. All is good now. Thanks for your help.
