BRAKE HOSES AND LINES

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 68

Fig. 2: Rear brake lines
Metal lines and rubber brake hoses shou ld be checked frequently for leaks and
external damage. Metal li nes are particularly prone to crushing and kinking
under the vehicle. Any such deformation can restrict the proper flow of fluid and
therefore impair braking at the wheels. Rubber hoses should be checked for
cracking or scraping; such damage can cr eate a weak spot in the hose and it
could fail under pressure.
Any time the lines are removed or di sconnected, extreme cleanliness must be
observed. Clean all joints and connecti ons before disassembly (use a stiff
bristle brush and clean brake fluid); be su re to plug the lines and ports as soon
as they are opened. New lines and hoses should be flushed clean with brake
fluid before installation to re move any contamination.
