Reinforced brake drum for Vespa PX, T5, LML 2T, Cosa 10"
This is an optimized 10 inch
Vespa brake drum from Scootopia. This drum simply replaces the old part and features a massively reinforced steel core with significantly larger aluminum struts on the inside. Externally, it is fortunately very similar to the original brake drum,
the original look is retained!
With the original Piaggio brake drums, it was possible to change the stud bolts, but this was no longer possible with the repro drums available afterwards. With this new Scootopia drum, the
wheel studs can be replaced again, which is practical if a thread is defective. It is also inexpensive and sustainable at the same time, as only one stud is replaced instead of a complete drum.
Our recommendation for Vespa Largeframe Tuning
Thanks to its solid construction, the Scootopia brake drum offers significantly more safety. This makes it the preferred choice for all powerful tuning engines.
Does the brake drum fit my Vespa
? The drum fits all Vespa engines with a Ø30mm shaft seal. If the
shaft seal is also replaced (see below), it fits almost
all largeframe engines with 10 inch tires. Can
therefore be used for Vespa Sprint, Rally, TS, GT, GTR etc.
Background knowledge 10 inch Vespa brake drum:
With the introduction of the Vespa GL around 1962, a new type of brake drum was established for the rear wheel shaft, which is still used today in almost the same design. With the exception of the GS160/SS180 and COSA models, this type of drum was fitted in all Vespa scooters from 1962 onwards with a horizontal cylinder (Vespa Largeframe).
- 1962-1984: Drum with Ø27mm oil seal running surface, castle nut secured with split pin. Tightening torque: 75-90NM
- 1984-1988: Drum with Ø30mm shaft seal face, hexagon nut secured with cage and split pin. Tightening torque: 90-110NM
- 1988-today: Drum with Ø31.5mm unground running surface for felt ring, hexagon nut secured with cage and split pin (the actual oil seal is located in the gearbox). Tightening torque: 90-110NM
The constantly increasing flange diameter (from Ø27 to Ø31.5mm) enables a significantly more stable brake drum flange. The models with only Ø27mm tend to expand quickly if the tightening torque was too low. A splayed brake drum flange can be recognized by a rear wheel that keeps loosening, despite a correctly tightened rear wheel nut. The only remedy here is to replace the brake drum in good time, otherwise the
splines of the main shaft will be
affected and must also be replaced. For stability reasons, it is always advisable to change to a drum with a 30mm flange diameter.
BRAKE DRUM CONVERSION
OLD TO NEW (27mm => 30mm)
The more stable drum of the PX Lusso models from 1984-1988 can also be used on the older model years with Ø27mm drums, provided that the shaft seal ring of the Lusso models with Ø30mm and the washer of the models from 1984 onwards are also used.
BRAKE
DRUM DOWNGRADE new to old (31.5mm => 30mm)
The latest type of brake drum (1988-today) no longer has a ground running surface and is therefore unsuitable for combination with a shaft seal. An internal shaft seal and external felt ring were used ex works on models from 1988 onwards. The Lusso drum from 1984-1988 can also be used here and converted to a conventional oil seal (TIP: If the internal oil seal is omitted here, please be sure to close the drip hole in the housing.
