Road salt in Michigan destroys brake lines, fuel lines and subframes from underneath, and it does it years before the paint shows a single bubble.
At a glance
- Brake and fuel lines fail first because they sit lowest
- A rusted subframe or strut tower can fail a car outright
- Catching it early turns a $4,000 job into a $400 one
- We photograph the whole underside so you see what we see
Ask anyone who has owned a car here for ten years. The body can look clean while the parts you never see are rotting. Salt sits on top of horizontal metal, holds water against it and keeps working all winter.
The parts that go first are the ones bolted lowest. Brake lines. Fuel lines. Exhaust hangers and flex joints. Then the harder structure follows, and that is where it gets expensive. A rotted subframe mount or strut tower is a safety problem and sometimes a reason to stop putting money into a car.
There is a window on almost every one of these. A brake line caught while it is scaly costs a couple of hundred dollars to replace. The same line caught after it bursts costs you a tow, a full flush and whatever the car hit.
We run an underside check on every car we visit, whatever we were called out for. It costs you nothing extra and it goes on your job page with photos. If your car is clean underneath we tell you that too.
Common questions
Is undercoating worth it here
On a car that is already clean underneath, yes it buys you years. On a car that is already scaling it can trap moisture and make things worse. We look first.
Can rusted brake lines be patched
We flare and fit new line. Compression fittings on a brake system are a shortcut we will not sell.
When is a car too far gone
When the structure the suspension bolts to is soft. We will tell you plainly and we will not quote a repair we do not believe in.
