TurboBrake HB427-H 2-Piston Brake Calliper

• TurboBrake HB427-H is eScootNow's recommended entry-level hydraulic calliper (2-Piston).
• Proven reliable as stock calliper on Dragon Langfeite models of Dragon Predator, Hurricane & newer models of Cyclone Pro, Lightning V2 & Beast. Teverun also introduced this calliper on the Fighter Mini & subsequent Blade Mini hydraulic models and Blade GT (II).
• HB427-H is a good calliper replacement option for most makes/models of eScooters where 2-piston is adequate.
• H designation = hydraulic (2-Piston). This is a contemporary calliper with similar performance of other 2-piston callipers such as those from Logan, Zoom and NUTT.

• Available in Left or Right orientation. This orientation defines the location of the hydraulic line termination (banjo bolt) as you look at the outer side of calliper mounted on scooter. For example, a calliper with right orientation, sitting on top of swing arm will suit rear right hand side of scooter & front left hand side. It will also suit front right hand side if located "behind the fork". See notes for further info, as a general guide:
  • NAMI = Left.
  • Kaabo Warrior = Right with exception to the GTR which adopts Left at front.
  • Kaabo Mantis 8/10 = Left.
  • Teverun Fighter = Left.
  • Dragon Predator (Langfeite C5) = Left short (for front) Right long (for rear).
  • Dragon Hurricane = Right orientation.
  • Dragon GTR (including V2) = Short Right (for front RHS behind fork) and Right Long (for rear RHS on top of swing arm). Factory stock bracket for the cable/mechanical calliper cannot be re-used as length is too short.
• Supplied with Long or Short hydraulic line (hose), industry standard BH59 type with TEKTRO style barb.
  • Short, for front is 1.28 meters (1280mm) length.
  • Long, for rear is s 2.1 (2100mm) meters length.

Lengths are derived from that of NAMI Logan 4-Piston (Burn-e) which is the most generous of all common 11" wheel scooters.

Hose terminates on the outside with a Banjo Bolt. The Banjo provides flexibility for routing of hydraulic line (hose) at expense of more points-of-failure. In contrast, the 4-piston HB427-4S calliper is without Banjo.

• Supplied with factory fitted Hook pad (resin semi-metal). Replacement pads are offered in choice of 4 compounds.
• Includes 7-piece kit comprising of olive (bushing), compression nut, cover (hood/boot), pair of M6 x 18mm socket head bolts with washers to secure bracket to swing arm and 6x1.0 O-ring for the factory-fitted TEKTRO barb.
• There is branding on Right Short of ST (Showtime FMX High Octane Entertainment) and Right Long is TurboBrake, branding is on outer face of callier. The Left's are without branding.

Notes:

1. Typically paired with the TurboBrake Lever or the higher end CNC Ball Bearing Edition lever.
2. This is the OEM calliper factory fitted as stock on most newer Dragon (Langfeite) mode of Cyclone, Predator, Hurricane, Lightning & The Beast.
3. Examples of orientation adopted on popular makes/models (always check your own build):
   1. NAMI has Left orientation.
      Rear is on the left hand side above swing arm, hence Left. Front is on the right hand above swing arm on Burn-E and Klima, and on left behind the "forks" on Blast which are all Left orientation.

   2. Kaabo Wolf Warrior Series has Right orientation with exception for GTR front.
      
      
   3. Dragon Hurricane has Right orientation.
      Rear is on the right hand side above swing arm, hence Right. Front is on the right hand side, behind the "forks" hence right.
      
      
4. Advice relating to bleed adaptor on HB427-H calliper:
   This advice can also be considered for models using this calliper such as Teverun Fighter Mini, later models of Blade Mini & GT (II) and the Dragon / Langfeite models such as Predator, Hurricane & newer models of Cyclone Pro, Lightning V2 & Beast.
   
   The bleed screw thread is M4, as shown below (on the left). These adaptors are included in the common eZmtb bleed kits (kits usually have two of these adaptors). All other TurboBrake callipers (such as 4S and 4M) use the TurboBrake M5 bleed adaptor.
   
   
   Likewise the levers typically paired with eScooters with HB427-H callipers are likely to be (or identical to) TurboBrake levers. Such levers use the TurboBrake M5 bleed adaptor as shown below (top right). The M5 adaptors in eZmtb bleed kits are typically not sufficiently long enough for the levers, so you may need a TurboBrake M5 bleed adaptor to bleed the accompanied levers.
   
   
   Image below contrasts the M4 and M5 adaptors.
   
   
5. Typically the existing, factory stock brackets are retained as TurboBrake callipers are intended as drop-in replacements having similar shape and pad placement as most stock eScooter callipers. This section explains brackets - the two common IS ones used across 140 and 160mm rotors.
   • The F-180 R-160
     This is the common taller bracket: 22 & 22mm offset (height).
     Supplied with HB427-4S left long (also available as 002 from MUQZI).
     • This bracket is adopted on NAMI Burn-e, Kaabo Wolf Warrior 11/GT Series and Factory Teverun Fighter 11 front/rear. Note some Wolf Warrior's are observed with a 19 & 19 ("no washer") bracket, which is effectively a 22 & 22 shaved down 3mm.
   • The F-160 R-140
     This is the common shorter bracket: 11mm & 7mm offset (height).
     These are supplied with HB427-4S shorts (left & right) and right long (also available as 001 from MUQZI).
     • Adopted on NAMI Klima. Near identical to that of the Kaabo Wolf Warrior King/GT rear (Wolf is precisely observed as 12/7mm).
   • The above inclusions of F-160 R-140 on the right long is a deviation from the usual TurboBrake build, whereby normally a F-180 R-160 is supplied on longs and F-160 R-140 on shorts.
6. Special purpose brackets are often used if intending to fit a larger rotor or relocate the calliper to be more favourable with clearance. MUQZI has an extensive range of special purpose brackets. Here is a couple of relevance:
   • IS 004 F-203 R-180 shown as blue bracket bottom right as an alternative to F-180 R-160. Used when fitting +20mm larger rotors as shifts the calliper position "away and across" making it an ideal candidate for 160mm -> 180mm rotor uplifts. The actual bracket with that Magura is likely the 007 R-203.
   • PM 005 F-203 R-203 shown as blue bracket top right, it is a (PM: Post Mount) stacked with an IS F-160 R-140. The objective here is to shift the unorthodox sized Magura MT5e calliper and banjo bolt away from the tyre sidewall. The IS 007 R-203 is also a candidate. You generally need not do need special purpose brackets for TurboBrake if retaining stock size rotor.
     .
     
     The IS naming convention is industry standard convention, however often a different type of bracket to what the nameplate numbers suggest. For example, the Klima has stock 140mm rotors yet still requires an F-160 R-140 on the front. You cannot just go by the numbers - you can usually go by increments (e.g. +20mm larger rotor).
7. ABS Spacers from Grey Eteri Store and HUJI Store make a tidy finish compared to stacking washers when fine-tuning placement. Use M6.2 internal diameter for the M6 bolts, 9mm external diameter. Similar to the M5.2's in the TurboTight NAMI Klima Fender Spacer Kit. Alternatively you could use 6x8 or 6x10 copper sleeve from AN DE LI Hardware Fitting Store or U Officer Store.
   
   
8. Image below shows the hydraulic line (hose) supplied with TurboBrake callipers to connect to the brake levers that adopt BH59/TEKTRO fittings such as TurboBrake Levers. This calliper includes the type on left, identical to the TurboBrake 4-piston HB427-4S hose. This is a TEKTRO style fitting (hence the inclusion of BH59 insert (needle/barb) with washer). Calliper includes 7-piece kit includes 6x1.0mm o-ring washer on the factory-fitted barb as shown below. The compression nut adopts the common thread of M8 (0.75 pitch) adopted by most eScooter brake levers, allowing connectivity to existing levers such as Zoom, Logan and NUTT. The steel braided flexi whip hose shown on the right with factory crimped fitting is the higher-end TurboBrake HB427-4M calliper. Refer to the TurboBrake Reference page for further information about hose and insert types such as Shimano BH59, BH90 and TEKTRO.
   
   
9. Bracket offset (height) is the 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. Sometimes brackets are labelled with a nameplate on the underside. Image below contrasts some of the brackets as observed on Kaabo/Zoom callipers:
