BMW 1 Series M Brake Hose Replacement at your home or office.

When to consider replacing the brake hose:

• Physical damage. If there are cuts, cracks, abrasions, bulging, or excessive rust at the hose fitting ends, the hose should be replaced.
• Leaks. Seepage at hose fittings, or leaks anywhere along the hose, requires replacement. If there is a leak, or the hose is bulging, you may notice that the brake pedal is lower than usual or spongy.
  
• Internal hose failure. Occasionally, the lining on the interior of the hose can separate, blocking the flow of hydraulic fluid. This is diagnosed using test gauges. A fluid blockage that prevents the brakes from releasing may manifest itself as dragging brakes or overheated brakes.
  
• End of Lifetime. Although many brake hoses can last 20 plus years if well-made out of quality materials, after 10 years of service it is best to replace the hoses with new ones for maximum reliability and safety.
