The Vespa ET2/ET4/LX/LXV/S models are supplied with a nice looking HENG Tong brake calliper. As this component isn't exactly state-of-the-art we have manufactured a brake caliper which not only sets the pulse of any professional customizer racing, but also improves the braking effect of the disc brakes.
The SIP Performance brake calliper is CNC-milled completely from aluminium. The bigger piston diameter, totalling 31.5 mm, guarantees a better braking performance. We have also given the brake calliper a GALFER brake pad that has a bigger pad width and therefore a non-tilting bearing surface. Special additional inner drill-holes make the bleeding easier. The brake callipers are anodised and come in the extreme racing colours of silver, gold, black, titanium and red.
Please note: The brake calliper can be fitted to all classic Vespa models, which are using a ZIP SP conversion column.
SIP has been successfully verified by the German ministry of transport and is now officially recognized as approved vehicle component manufacturer. The SIP brake caliper has also received official type-approval. The brake caliper SIP MV5642 got the German KBA number 61372. They managed all the necessary tests for a legal road-use on German roads. For sure, this will help also to legalize it in other countries.
Conclusion: Style update for the style queen ‚Modern Vespa‘.
SIP-TIP: Use new brake fluid! A Stahlflex (braided steel) brake hose completes the picture and gives an even more accurate pressure point. If you lose the ball bearing for the bleeder valve you require the packet seal (part no. 56409000).
- Turn the brake calliper a couple of times during the venting
- In case of a semi-hydraulic transducer, disengage bowden cable in order to get the complete lever stroke
