I would suggest a deep interior clean too

thanks for the video, a brake line broke off while i was driving my truck a 2003 tundra 4x4, after i installed a new brake line i cant bleed the rear brakes, very little fluid comes out of the bleeding screws, you think its air inside the abs ?

Nice video. I have a 2004 Toyota Tundra SR5. I had to replace my brake booster because it had a leak inside the cab area. I purchased an aftermarket booster from Autozone but believe it might have been defective. Ever had air coming out between cylinder and booster? I got a code for running lean and it's all I could find that might be causing the problem. Do you think it's better to get an OEM part? What are your thoughts?

Maybe the check valve not good, because the make air return to intake,

How about the valve. Can you test it?

How do you test master cylinder
