5 Cautions When Changing the Brake Oil Pipeline

1. Attention To Safety

The process of replacing the automobile brake hose to the bottom of the car will be very dangerous if the repairer does not notice some problems:

  • Fully equipped with gloves, clothes, hats, special glasses to prevent brake fluid from sticking to the body. It is extremely dangerous to let brake fluid in the eyes.
  • Raise the car slowly, taking care to avoid overturning.
  • Prepare a cleaning cloth, tray or brake pad to prevent the oil from falling onto the floor, causing dangerous slippage.

2. Completely Replace the Brake Oil Pipeline

If a car brake fluid pipe has problems only at a certain part of the pipeline, would it be too wasteful to replace all the pipes?

Actually replacing an oil pipe is just a temporary "fire fighting" solution. The joints in the old pipe section and the new one are very easy to rust and continue to leak the oil pipe. The best way is to replace the entire brake hose pipe so that the brake system works as smoothly as possible.
