• 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 with factory-crimped Banjo Bolt and pre-fitted to the calliper with washers and screw. The other end is fitted with a BH59 (gold) needle with threaded head with capped, pre-bled and terminated to lever with the optional 3-piece kit. Lengths of:
  • Long, for rear. Kaabo Warrior 11/GT spare is 1900mm length. Teverun Fighter 11 is 2100mm length.
  • Short, for front. Kaabo Warrior 11/GT spare is 1140mm length. Teverun Fighter 11 is 1230mm length.
• Callipers are supplied with bracket / adapter (not pictured) that mounts the calliper. There are two common types:
  • F-160 R-140 bracket:
    8mm & 12mm offset - as adopted Kaabo Wolf Warrior King/GT rear, or
  • F-180 R-160 bracket
    23mm offset - as adopted on Kaabo Wolf Warrior King/GT Series front and Factory Teverun Fighter 11 front/rear.
    
    If renewing, typically existing brackets are used. The designation does not necessarily relate to the brake disc rotor size (mm). For example, Warriors have 160mm rotors use a a F-160 R-140 size bracket on rear.

  • Include olive/bushing only

The compression nut and cover can be re-used when renewing, bushing/olive is typically single use.

Notes:

1. This calliper has no designation (no model number).
2. For brake pads, use catalogue item: Semi-metal brake pad suit Zoom Hydraulic.
3. Levers are also available as a separate product item: Zoom Hydraulic Brake LeverSeries.
4. The hydraulic line has a factory fitted banjo connector with bolt. It is not serviceable nor supplied individually. 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. Image below shows a Zoom banjo bolt that has reached end of service life -note the deformations on the metal.
   
   
   
   
5. 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.
6. 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.
   
7. The e or -E prefix designation applies to the electric brake switch on the lever.
8. US spelling caliper.
