Bleeding Harley Brakes

How to bleed with and without ABS.

Harley-validated

Without ABS

  • Pump the lever, hold, open the bleeder, close, release lever
  • Repeat until clean fluid comes out with no bubbles
  • Keep the reservoir topped up

With ABS

  • Normal bleed at the calipers
  • To cycle the module: you need a J1850/CAN scanner
  • Use service mode on Digital Tech or Dynojet

Safety & cautions

  • NEVER pump the lever with no fluid — pushes piston and leaks
  • Use ONLY DOT 4 (Harley system) — DOT 5 silicone only on specific pre-2006 bikes
  • Test brakes at low speed before hitting the road
  • New pads: 100 miles of bedding-in, no hard braking

Average US cost (USD)

  • DIY front pads: $40-90 a pair (EBC, Lyndall, Galfer)
  • Dealer pads + bleed: $220-380
  • New front rotor pair: $300-600
  • Brembo radial upgrade: $1,500-2,800 installed

When to see a mechanic

  • Lever goes to the bar even after bleeding
  • Visibly warped or wavy rotor
  • ABS warning stays on

Quick questions

Can I use car brake pads?
No. Different compound and shape — works worse and is illegal in the US.
How long do pads last?
Front: 10-15k mi. Rear: 15-25k mi. Loaded touring cuts that by 30%.
