Zoom DB-03 Brake Pad

• This pad suits the Zoom HB-875 2-Piston hydraulic callipers which are factory stock on makes/models such as:
  • Kaabo models (calliper is usually Kaabo branded) of:
    • Wolf models including Warrior X, 11 (including King), Warrior GT series (including King GT) and King GTR.
    • Mantis Pro.
  • Dragon models of:
    • Pre 2024 models of the Dragon Lightning series (such as Lightning V2 pre-2024) and The Beast, typically red calliper with white Dragon branding.
    • The Dragon Slayer (and the similar Bolzzen Commando inaugural model) which is Joyor S Series OEM.
  • Most of the VSETT models that have hydraulic brakes (VSETT branded Zoom callipers).
    • Exception being the inaugural VSETT models which had a NUTT A5-D calliper with NUTT YD-01 pads.
  • Zero models of:
    • "Zero 10X and Zero 11X" and ODM variants of the DDM-T10 and DDM-X11 that equipped with hydraulic callipers, noting hydraulic exceptions of:
      • The Zero "Limited" models which has a NUTT A5-D calliper with NUTT YD-01 pads.
      • The Zero mechanical/cable brake have a JAK-8 V calliper and use a "Crown" pad.
      • Dragon branded Hunter X10/X11 uses a NUTT A5-D calliper with NUTT YD-01 pads
  • Early versions of Teverun Fighter Series. Later entry level Fighter and Blade models use HB427-H calliper with Hook Pad and later flagship Supreme models HB427-4M with Logan 4-Piston pads.
  • InMotion RS / RS Lite.
  • Various other models such as those from KuKirin, Mercane and Veloz (e.g. G2 Master).
• Supplied as a set (pair) two pads, one for each side with retaining spring, no split pin. Order two sets for both front and rear.
• Organic resin semi-metal compound, does not need to warm up to be efficient.
• Retail packaged, akin to bulk pads from Zero USA and FalconPEV.

Notes:

1. Image below shows left-to-right:
   1. This Zoom pad
   2. Shimano B01S/M315 (slightly wider, Semi Metal variant for Logan 2-piston)
   3. NUTT YD-01 Cooling Enhanced,
   4. The non-finned NUTT pad (from factory as Zero NUTT calliper)
   5. The "Crown" pad, which will pretty much fit in any calliper of rectangular shape near this width.
      
      Note the variance between first two and last three with respect to:
      1. the shape of pad (pad placement / contact surface engagement area to the rotor).
      2. distance from the hole to bottom of pad surface.
         
         
2. The Zoom full hydraulic calliper requires a pad that is slightly narrower than the Shimano BN01S/M315 pad which appears identical, however there is typically 0.5mm difference in width.
   In order to fit into the Zoom calliper, the pad needs to not exceed width of 30.1mm. As a general rule, only the specific Zoom branded, retail packaged pads provide assurance of the pad being within that 30.1mm tolerance. The pad compound is organic resin semi-metal and this is the only type produced by Zoom. If you want to run alternative compounds, you will need to shave down approximately 0.4mm on each side to reduce the width of the plate (hand file is sufficient) on the Shimano B01S/M315 size pad. To further understand merits of each compound, refer to the Brake Pads Category homepage.
   • Image below shows contrast of this pad with slightly wider Shimano BN01S/M315 pad, which cannot fit in the calliper.
     
     
3. This image from an AliExpress seller shows various Zoom branded pads, suggesting this pad is DB-03 designation, although compatible callipers has no relation Zoom callipers on eScooters. The callipers DB680 and DB330/331 are all cable brake systems.
4. Here are some photos of inappropriate "Crown" shaped pads pulled out of a Zoom calliper in a Wolf Warrior King GT Calliper after 1000kms. The pad lacks sufficient depth, therefore not recommended for use in Zoom callipers. This "Crown" Pad is often described as suitable for VSETT 10+ (Ride Electric) and suitable for VSETT and other Zoom models (Bike Scooter City). While the crown will fit, due to having less depth the lower area of pad wears prematurely, impacting performance and longevity. This is explained further on the Crown pad product page. There are a lot of pads out there in the field that aren't appropriate and don't assume the pad in your scooter is the correct one - check yours!!!
   
   
   
   
5. You can appreciate the outcome of prolonged use of inappropriate pad, as shown below on NAMI Burn-E 2 (Non-Max with Logan 2-piston calliper). Again, the Crown pads, this calliper should be fitted with the deeper Shimano B01S/M315.

7. Image of InMotion RS / RS Lite brakes which uses HB-875E calliper with a HB890E series lever, which differs from the lever typically paired with the Zoom HB-875E calliper on most other makes/models. The lever has 3-pin ebrake switch *suggesting hall type) which is understood to support variable regenerative braking, rather than traditional binary on/off.
