BRAKE HOSE INSTALLATION INSTRUCTIONS

NOTE: READ INSTRUCTIONS THO
ROUGHLY BEFORE INSTALLATION WORK BEGINS

ATTENTION: Refer to the appropriate shop manual for your vehicle to obtain specific service procedures for this part. If you do not have a service manual or lack the skill to install this part, it is recommended that you seek the services of a qualified technician. Pay special attention to all cautions and warnings included in the shop manual. Read and follow all instructions carefully.

A steel brake line may be permanently attached to the brake hose on some vehicles (figure 1). This replacement hose is designed without the permanent steel line. You must obtain the correct length of steel brake line and make the appropriate bends (figure 2).

  • If the steel brake line being used is already equipped with flared fittings, the fitting provided with this hose can be discarded (figure 3).
  • If fabricating the steel line with bulk tubing and a double flare tool, the fitting for the end that will connect to the hose is included with the hose (figure 3).
  • The end of the hard line attaching to the vehicle’s system must match the style already on the vehicle (inverted double flare or ISO flare).

This procedure should be performed by an experienced technician.
