I was even a little confused. Didn't know what you were trying to prove. The comments cleared up that the brake booster was suspect. I'm assuming it was leaking while the pedal was being pressed. Pumping the pedal, the reaction shown would be normal.

Mike on the video I show that the fuel trims are running lean and when I pinch off the line to the brake booster the fuel trims drop. That lets us know that the leak looks like it’s coming from the brake booster. Does that help ?

@tylerfochtman15784 жыл бұрын
Hmm. Makes me wonder. On my 05 pathfinder I have the p0171 bank 1 lean code. Haven't done the brake booster check, seems intriguing. Always felt like I may have messed up something with my brakes when I changed them and never bled them out. Seem to drag a bit. When my car gets hot, or if the ac is on for a while, the short term bank one trims go to 25%
@joshbrewer9786 Жыл бұрын
Hey Oz, thanks for the video. When changing the brake booster do you do the master cylinder at the same time or is it fine to put the new power brake booster in and the old master cylinder? I am a contractor not a mechanic but I wanna do this one myself cause it’s easy to get to haha. I have a 2010 Nissan Frontier SE with 90k miles on it and ABS light/VDC OFF light and SLIP light all on with the PO171. I am hoping the Power Brake Booster solves all as no other codes come on that give any idea why all other lights came on same time check engine light did. If you have any thoughts before I do it let me know please. Otherwise I will do the Booster replace and clear codes and check back in here. Thanks Oz!
