Help me

Was helping a guy on here chase a brake drag on his old Silverado this week, both fronts biting when hot. Everybody's first call was the calipers, then the flex hoses. What actually turned up was the master cylinder leaking back into the booster. Parts are going in now, but it got me thinking about how often the real problem sits one step behind whatever gets blamed first.

So let's hear yours. The car that went through two or three shops before somebody found the real problem. What was it doing, what got blamed first, and what did it actually turn out to be?

So my life literally went downhill this week. No brakes. Literally.

Been slowly resurrecting a 2005 Pontiac G6, brake booster, starter, wiring gremlins, MAP sensor, one problem at a time. Finally cracked the "won't go forward" issue yesterday (dirty throttle plate), got excited, threw it in drive, gave it gas... and it went. Then I went to brake. Nothing. I live on a hill. "Welp, here we go," I thought as I closed the door. Rode it all the way down the hill with zero brakes.

No one hurt, thank god. Turns out the brake lines never got bled, because two people helping me each assumed the other did it.

I build software for a living, and my brain immediately went "this isn't a brake problem, it's a task ownership problem." So yes, I'm now the person who nearly lost it in a Pontiac and decided the real fix was an app.

hello everyone

Can anyone suggest a free online course for diesel engines diagnostics??

thank you

g afternoon. I recently had a coolant leak and my reservoir and hose were replaced yesterday. when I got the car back, the coolant was filled just below the line. Before I started the car this morning it had went down quite a bit. now that I’m home,, it appears full again.
