  • Kaabo models of Wolf Warrior X & 11 including King, Wolf GT, Wolf King GTR and Mantis 10 models Pro, X & King GT.
  • Select Teverun and Blade models such as select Fighter and Mini.
  • VSETT models such as 10+ and 11+ (earlier models were equipped with a NUTT A5-D calliper including Super 72 variant).

  • Early Dragon models that adopted Zoom systems (e.g. Lightning V2).
  • Various other models such as those from KuKirin and Mercane.

• Available in Left or Right version. This orientation defines the location of the banjo bolt (hydraulic line termination) as you look at the side of the calliper. For example, a calliper with right orientation that sits on top of swing arm will suit rear right & front left and also front right if located behind the fork.
  • Kaabo typically adopt Right versions on Warrior models with exception to the GTR which adopts a Left at front. Kaabo Mantis 8/10 and Teverun Fighter adopts Left versions.
• Supplied with Long or Short hydraulic line. These are BH59 type hose with factory-crimped Banjo Bolt and pre-fitted to the calliper with washers and screw. The other end is fitted with a insert (barb/needle) with threaded head with capped, pre-bled and terminated to lever with the optional 3-piece kit. Lengths of:

Notes:

1. Refer to the TurboBrake Reference page for further information about hose and insert types such as Shimano BH59, BH90 and TEKTRO.
2. This calliper has ambiguous designation as a different Zoom calliper typically not on eScooters which adopts a hook pad also has HB875E designation.
3. For brake pads, use catalogue item: Semi-metal brake pad suit Zoom Hydraulic.
4. Levers are also available as a separate product item: Zoom Hydraulic Brake LeverSeries.
5. Image shows various brackets observed on Kaabo and Teverun spares.
   
   
6. The hydraulic line has a factory fitted banjo connector with bolt. It is not serviceable nor supplied individually (economically). It is proprietary and not common with any other brand calliper. If you can ascertain the washers inside the banjo bolt are damaged, you could renew them however it is best to renew the calliper and run a new hose which is supplied with calliper. 3rd party banjo's, such as that on common "Shimano SLX/XTY/XTR" Banjo's do not fit (and also run smaller inner diameter BH-90 hose). Banjo's are troublesome and an unnecessary point of failure - best to avoid them. 3 o-rings: one 4x1.5mm & two 5x1.5mm, my go to's. Image below shows a Zoom banjo bolt that has reached end of service life - note the deformations on the metal.
   
   
7. Bracket offset is distance from centre of threaded hole in the bracket that connects to the scooter to the surface of the edge of bracket where the calliper sits. These brackets are typically labelled with a nameplate on the underside.
8. eScootNow also stocks Logan 4-Piston callipers as NAMI spares which adopt Left orientation. Zoom's inaugural 4-Piston HB-876 is a rebrand of the Logan calliper (shown below on left), Zoom subsequently released their HB-890 which is a non-Logan version (different shape, terraced profile) shown on right.
   
9. The e or -E prefix designation applies to the electric brake switch on the lever.
10. US spelling caliper.
