Detailed Description

TOST Hydraulic Retrofit Kit – 4″ Liliput Wheel

General Description

Hydraulic actuation of TOST shoe brake wheel Liliput (Libelle, LS1, LS3*, Diamant, SF27, ASW15*, Salto, Phoebus, PW5* and others) *not all models, call for information. To improve the braking force, all 4″ TOST shoe brake wheels Liliput can be actuated hydraulic in the future. This eliminates loss in the brake force due to the friction of the existing mechanical cable actuation. With the hydraulic actuation the braking is considerably improved and can be better dosed. This conversion allows you to keep the existing wheel.

Please note: For wheels more than 30 years old, the complete wheel hub may have to be exchanged.

Please allow approximately 4 weeks delivery time for your TOST Retrofit Kit.
