Hydraulic brake bleed needed
MaintenanceLevers slowly losing firmness, pulling closer to the bar over months, or after the bike was stored upside down.
Typical repair cost: $60-$140 including parts and labor. You get an estimate before any work starts.
Likely causes
- Air migration into lines over time
- Micro-leaks at fittings
- Fluid degradation
- Storage or transport position
How it gets fixed
- Full hydraulic bleed (mineral oil or DOT per brand)
- Fitting inspection and reseal
- Lever/caliper service
Try this first
Hydraulic systems need a bleed roughly every 1-2 years of regular riding. Use the correct fluid: mineral oil brands (Shimano, Magura, Tektro) and DOT brands (SRAM, Avid) are NOT interchangeable and the wrong fluid destroys seals. This job needs brand-specific bleed kits, which is exactly what a mobile tech carries.
