Secondary ignition diagnostics are often overlooked in modern vehicles due to coil-on-plug systems—but the waveform still tells a powerful story. In this video, secondary ignition waveforms are captured and analyzed using an oscilloscope to reveal what is actually...
Today we’re rebuilding the rear brake calipers on a DeLorean — a job that solves common issues such as dragging brakes, uneven pad wear, sticking pistons, and handbrake imbalance. The DeLorean’s rear calipers have some unique design quirks, including the integrated...
Learn practical lab-scope workflows you can use today. We reinforce the basics with real-world tests: checking primary ignition current with a low-amp probe, verifying an entire bank of coils via the common power feed, reading fuel-pump current through a fuse-loop...
Everyone’s talking about how bad the automotive industry is right now — low pay, burnout, lack of respect, and technicians leaving the trade. But that’s only half the story. In this video, I talk about what’s really going on in the automotive world — and why it’s not...
In this next issue, we talk about brake fluid. I was looking forward to making this one. It is a really important one. Brake fluid might be out of sight, but it should never be out of mind. In this video, we explain what brake fluid is, what it does, and why neglecting it can lead to dangerous brake failure. Most drivers don’t realize brake fluid is hygroscopic—it absorbs moisture, and over time, that can corrode your brake system from the inside out.
🚘 Here’s what you’ll learn:
What brake fluid is and how it works
Signs of bad or contaminated brake fluid DOT 3 vs DOT 4 vs DOT 5.1 – what’s the difference?
Why moisture in brake fluid is dangerous
How often to flush brake fluid (OEM recommendations vs reality)
ABS, traction control, and stability systems and their reliance on good fluid
How dirty brake fluid damages calipers, master cylinders, and more
Why brake pedal feel can be affected
This is essential maintenance for Subaru, Toyota, Honda, Ford, GM, and other vehicles with ABS and modern braking systems. Whether you’re a DIYer or just trying to protect your investment, this video helps you stay safe.
🧪 Don’t skip this—your brakes literally depend on it.
