Chapter 4 Sabotage #2
Let the evidence speak.
He began with the master cylinder.
The fluid reservoir sat well below normal.
Interesting.
Not empty.
Just low enough to cause dangerous pressure loss.
He checked every visible connection.
Dry.
No obvious leaks.
Next came the brake booster.
Everything appeared normal.
The steel brake lines running beneath the chassis became his next focus.
He slid beneath the ambulance on a mechanic's creeper, flashlight in one hand and inspection mirror in the other.
Rain drummed steadily against the roof overhead.
The garage lights reflected softly off polished steel and aluminum components.
Slowly, inch by inch, he followed the hydraulic lines from front to rear.
His flashlight paused.
Brake fluid.
A single fresh droplet clung to one section of steel tubing before falling silently onto the concrete floor.
"There you are."
He wiped the area clean with a cloth.
A few seconds later another tiny bead formed.
Small leak.
Not enough.
Something still didn't feel right.
A natural corrosion leak usually spread around fittings or rusted sections.
This one appeared strangely isolated.
Jax reached for a magnifying inspection light from his toolbox.
The brighter beam illuminated every millimeter of the brake line.
He frowned.
"What..."
He cleaned the surface again.
Looked closer.
Then looked even closer.
His heartbeat slowed.
The damaged section wasn't rusted.
It wasn't cracked from age.
It wasn't worn thin by vibration.
It had a shallow groove.
Perfectly narrow.
Perfectly controlled.
Almost...
No.
He slid farther beneath the ambulance until his face was only inches away from the line.
The groove wrapped partially around the steel tubing without cutting completely through it.
Deep enough to weaken.
Not deep enough to fail immediately.
Jax stared silently.
Someone hadn't wanted the brake line to break inside his garage.
They had wanted it to fail later.
Under pressure.
On the road.
His stomach tightened.
He carefully photographed the damaged section from several angles before measuring its depth.
The groove looked remarkably consistent.
Too consistent.
He walked to his tool cabinet and selected several small files.
One by one he compared the teeth against the marks on the damaged tubing.
Nothing matched perfectly.
Whoever had done this hadn't used an ordinary shop file.
Perhaps a specialty cutting tool.
Perhaps something even smaller.
He wasn't ready to guess.
Evidence first.
Conclusions later.
The garage office door opened.
His apprentice, Tyler Grant, stepped inside carrying two cups of coffee.
"You've been under there almost an hour."
Jax accepted the coffee absently.
"Thanks."
Tyler noticed the serious expression.
"Bad?"
"I don't know yet."
"You usually know."
Jax remained quiet.
Tyler crouched beside him.
"What are we looking at?"
Jax pointed toward the damaged line.
"What do you see?"
Tyler studied it carefully.
"Looks like..."
He stopped.
"No."
"What?"
"It almost looks cut."
"Almost?"
Tyler leaned closer.
"I've never seen corrosion make marks like that."
"Neither have I."
Silence settled between them.
Finally Tyler asked the question neither of them wanted answered.
"Think somebody did that?"
"I don't know."
"But if somebody did..."
He didn't finish.
He didn't have to.
Both men understood.
An ambulance had nearly crashed.
Not because something failed naturally.
Because something had been made to fail.
Jax stood and walked toward his office.
He opened a locked cabinet and removed every maintenance record associated with Rig 2.
Dates.
Inspections.
Repairs.
Replacement parts.
Everything appeared exactly as it should.
Including his own signature from the most recent brake inspection.
The system had passed every safety check.
He remembered performing it personally.
He trusted his own work.
Which meant the damage happened afterward.
His office phone rang.
He answered immediately.
"Cooper Auto."
"Jax."
Chief Harper.
"I need answers."
"I'm working on it."
"What do you think happened?"
Jax looked through the office window toward the silent ambulance.
"I don't want to speculate."
"I need your professional opinion."
Jax hesitated.
Years of experience told him never to accuse anyone without proof.
But years of experience also told him when something was terribly wrong.
"The brake line didn't fail from normal wear."
Silence answered him.
Finally Harper spoke.
"What are you saying?"
"I'm saying..."
Jax chose every word carefully.
"I found damage that doesn't look accidental."
"You think someone tampered with the ambulance?"
"I think someone needs to investigate."
Another long pause.
"I'll notify the sheriff."
"Don't move the ambulance."
"I wasn't planning to."
The call ended.
Jax remained standing in the office.
Outside, rain streaked across the garage windows while thunder rolled somewhere beyond the mountains.
His eyes settled once more on the damaged ambulance.
Then another image replaced it.
Julian gripping the steering wheel.
Julian driving downhill.
Julian making split-second decisions while trusting that the machine beneath him would do what it was built to do.
If the brake line had failed only thirty seconds earlier...
If there had been heavier traffic...
If Julian hadn't found the gravel turnout...
Jax stopped the thought before it finished.
He walked back beneath the ambulance one final time, studying the damaged brake line with renewed determination.
There was no doubt left in his mind.
This wasn't bad luck.
This wasn't deferred maintenance.
This wasn't mechanical failure.
Someone had deliberately weakened that brake line.
Someone had knowingly sent an ambulance carrying first responders onto the road.
Someone had been willing to risk lives.
And for the first time since taking over Cooper Auto Repair, Jax realized he wasn't investigating a broken machine.
He was staring at the beginning of a crime.
