Why are my Gilera Runner Purejet 2007 brakes overheating?

  Jacob RichardsonAug 2, 2025
  Your Gilera Scooter brakes might be overheating due to several reasons: * Defective sliding of pistons: Check the calliper and replace any damaged part. * Brake disc slack or distorted: Check the brake disc screws are locked and use a dial gauge with a wheel mounted on the vehicle to measure the axial shift of the disc. * Clogged compensation holes on the pump: Clean carefully and blast with compressed air. * Swollen or stuck rubber gaskets: Replace gaskets.

How to troubleshoot battery issues on a Gilera Runner Purejet 2007?
- C
  Chad FlynnAug 22, 2025
  To troubleshoot battery issues on your Gilera Scooter: * Frequently check that the fluid level fully covers the plates; otherwise, restore the level adding distilled water (never use natural water, even if it is drinking water) and check fluid density at the same time. * If the vehicle is not used for some time (1 month or more) the battery needs to be recharged periodically. * If the battery is fitted on a motorcycle, be careful not to invert the connections, keeping in mind that the black ground wire is connected to the negative terminal while the red wire is connected to the terminal marked+.
