Acura Coupes and Sedans 1986-1993 Repair Guide

Brake Lines & Hoses



The Acura anti-lock brake system contains brake fluid under extremely high pressure within the pump, accumulator and modulator assembly. Do not disconnect or loosen any lines, hoses, fittings or components without properly relieving the system pressure. Use only a bleeder T-wrench 07HAA-SG00100 or equivalent to relieve pressure.Improper procedures or failure to discharge the system pressure may result in severe personal injury and/or property damage.

The brake lines and hoses must contain brake fluid under very high pressure and do so without allowing leakage or contamination. If a brake line must be replaced, use a premade line or factory replacement part. Use care and a proper tubing bender when forming the new line. Use only DOT approved replacement brake hoses.

If a flare must be formed, use the proper flaring tool and very carefully inspect the work. The integrity of the braking system relies on safe connections. Personal injury or death can result from a brake line failure.

  1. Clean the area around the connection.
  3. Use a small brush to clean the joint at the nut and the brake line.
  5. Use a proper sized flare wrench on the nut and loosen the connection.
  7. Install the new connection so it is easy to thread the nut by hand to prevent crossthreading. Use a backup wrench where 2 lines meet.
