For serious off roaders, extended brake lines may be a necessity, not an option.
Extended brake lines will give you enhanced braking and better brake pedal response. Which can sound like an option of choice, but these days modern off road vehicles can be so powerful and so fast that constant heavy braking can mean you actually need extended brake lines for safety.
All the essential extended brake line questions, answered!
Do you need extended brake lines?
If you've got a high powered vehicle, like driving fast or taking seriously challenging tracks which require regular hard braking - yes!
If you have fitted an extended brake line and your suspension now has more travel than the original brake lines allow - yes!
Do extended brake lines improve braking performance?
Yes, but only if they are ADR approved stainless steel braided brake lines. The stainless steel braid prevents the internal hose from expanding under pressure leaving more brake fluid to do the job its designed for. Stop your car!
How long do brake lines last?
Of course this will depend on how and where your driving, and the component brand, but you should expect to replace them every 12,000 miles, or a year, whichever comes first.
Can you splice a brake line?
Yes you can if you have the knowledge and the right tools, and contrary to popular belief it isn't illegal to do so. But what you can't do is use compression unions or single flare unions for the brake line slice repairs, it's poor practice and it's dangerous.
How often should you replace brake lines?
The general consensus of opinion among mechanics is that brake lines that have worn down to 1/8 of an inch or less need replacing. inches or less - so all you need is tape measure.
Can I drive with a leaking brake line?
Absolutely not. Some may say you could drive home at least, but brake fluid leak can be flammable so we recommend you don't risk it.
How can you tell if your extended brake line is leaking?
Here are the vital signs that your brake line may be leaking:
- Leaking from under the car
- Your Brake Fluid Light comes on
- You can depress the brake all the way to the ground
- You can see moisture or signs of corrosion on the brake lines
- You have to pump the pedal a couple of times to get good braking performance
