Fork with disc brake system -LML Classic- Vespa PX Lusso (from 1984)

The Vespa PX models were never famous for their good brakes ...
Even Piaggio saw this and in 1998 gave the Vespa PX a modern brake update. A well-gripping and stable brake has been a series standard ever since.
From now on we offer you an inexpensive option to convert your old drum-braked PX to this modern technology!

All Vespa PX models built up to 1998 still have a drum brake on the front axle. It was only with the introduction of the PX Lusso in 1984 that it was improved and the fork and frame were reinforced, but it was never really possible to achieve proper braking power. In addition, there are the pitfalls of every drum brake, such as the unpredictable gifitge effect after a little downtime.

Anyone who has also given their engine a decent performance boost should not only think about a sensible and solid braking system for the TÜV. For many years, Grimeca was the top dog here with its retrofit disc brakes. However, due to the bankruptcy of Grimeca, this conversion option is no longer available.

An alternative would be original brake parts of the PX models from 1998. However, these have become almost unaffordable after the latest Piaggio prize round.

The perfect and also inexpensive solution is called Vespa LML fork!

The LML Star models, also known as Stella in the USA, are exactly the same model as the PX models, but made in India. The quality is on the same level as that of the Italian vehicles, an open secret is the fact that many of the switch scooter parts in the Italian vehicles now also come from Indian production.

The times when Far East production equates to poor quality can safely be put aside (even BMW has its engines for the F650 manufactured in China ...).

Due to our very good Indian supplier contacts, we can offer a very interesting alternative to the Grimeca disc brakes:

A complete fork, i.e.:

  • Steering tube
  • Brake hub
  • brake drum
  • caliper
  • shock absorber

completely assembled, from the ongoing production of the LML models.
The whole thing at an unbeatable low price, absolutely convincing in terms of quality.
It's not for nothing that our fast tourer has Silver-fern project received such a complete fork as well as ours Racer project with over 30HP parts of the LML brake used!

The fork fits plug & play in all frames from 1984. These have a combined ignition / steering lock function. The older PX models have the ignition lock on the lamp cover above the speedometer, the fork can also be used here, but for this a milling has to be made for the lock cylinder in the steering tube. But this can also be done at home with a little basic tools such as a drill and file. The original fork is sufficient as a copy template.

The pure brake without fork also fits all Vespa PK forks!

The fork is currently available with a brake drum in the style of the old PX models, ie with a closed hub!

MOUNTING THE BRAKE PUMP:

In order to be able to operate the brake properly, a brake pump is required on the handlebar.
Grimeca took the detour via partial hydraulics, ie a brake pump controlled by the original brake cable that was attached to the fork tube. A solution that largely nullifies the huge advantages of a hydraulic brake ...
In principle, fully hydraulic control, without a mechanical brake cable, is always the better because it is more efficient and more comfortable.
There are different ways of assembling a brake pump.

1. Modify the original handlebar

This solution requires a little more tools, manual dexterity and possibly composure than the second variant, since here a small part of the original steering head has to be irrevocably removed. We already have in ours how this is done Documented the project diary of the Silver Fern. The following parts are required for this type of conversion:

Brake pump NISSIN incl. Holder Braided steel brake line, mirror Brake banjo
Mirror 45 °		 Brake banjo
Spiegler Direct

2. Mount the new handlebar

The second solution is technically simpler because you only have to exchange parts.
The lower part of the handlebars on Vespa models built from 1998 onwards is used for this purpose. Both the original Vespa brake pump and the LML brake pump are available for this handlebar.
Both are identical in terms of their function, quality and appearance. Just not in the price ...

The following parts are required for this type of conversion (some alternatives):

Handlebar lower part Vespa PX from 1998 Brake pump -LML- Vespa PX from 1998 Pump PIAGGIO Vespa PX from 1998 Brake line PIAGGIO
Vespa PX from 1998
Brake banjo
Spiegler Direct		 Brake banjo
Mirror 45 °		 Brake banjo
Spiegler Direct		 Banjo bolt

Project Silver Fern, T5 fenders, front brake system

The Silver Fern needs a new brake system.

We use a complete LML disc brake for this. A T5 fender is to be mounted on the new steering tube. Since the T5 mud flap is a bit smaller, it is necessary to move the side holder.

The existing holder is therefore removed and the point at which it is to be welded on is prepared.

We bring the holder with the fender into the correct position.

After the holder is firmly connected to the steering tube again, we prepare the hole for the steel braided brake line.

The bore is widened to 9mm so that the connections of the brake line fit through.

We are still dipping the steering tube in fashionable matt black, we hope the new color scheme does not unbalance the sophisticated color concept of the Silver Fern too much.

While the paint dries, let's turn to the steering head bearings.

Special tools are required to remove the old shells.

With the plate ...

you get into the gap between the lower bearing shell and the seat.

The tool for the upper bearing shell ensures that the shell does not tilt in the head tube and widen the sensitive seat when it is removed.

When the old shells are removed, the new ones can be fitted with an insertion tool.

The steering tube is still drying. Therefore we only now turn to the handlebars.

The handlebars must be prepared accordingly for the brake pump holder.

We are taking this step-by-step.

Cut in first ...

... and then mill out to match.

We will replace the supplied Nissin brake pump with one of the current Vespa S / LX models.

The reason for this is the smaller piston diameter, the Nissen pump comes in the classic
1/2 inch format therefore, with a piston diameter of 12,7mm, while the pump of the Vespa S is equipped with an 11mm piston.

The smaller piston diameter enables higher braking power with less manual force.

The greater lever path due to the smaller hydraulic reduction leads to better controllability.

The adapter and the pump need to be adjusted slightly.

Fully assembled, it gives a very pleasing picture.

After the finished processing, the handlebar is also adapted to the new color concept and soon "shines" in matt black.

The steering tube is now dry. After the fender is mounted, the lower one
Open bearing shell and dust cover.

The steering tube is then inserted with plenty of grease for the bearings.

This one…

we replace with a set of new trains in Piaggio quality.

For the throttle cable, we use a universal throttle cable, the original Piaggio cable is unfortunately too short for the 28 Keihin.

After all the cables have been threaded in and the switch cables have been laid, the handlebars take their place on the new steering tube. We still have to come up with something on the subject of gas pipes. In order to open the 28er completely, the original gas reel would even be sufficient, but you would have to grasp at least once with the “tap open” movement.

This results in 2 solutions.

On the one hand, quick throttle grips are preferred, they give a sporty touch.

However, if you prefer a restrained look, you might be better off with a very inexpensive solution.

For some it is old hat, the pulley with stop.
There is no need to mount a suitable gas tube for quick throttle and the handlebars remain symmetrical.

Due to the conversion to a fully hydraulic brake system, there is no longer a brake cable running through the gas pipe, so we can freely choose the stop of the roller by positioning the screw.
However, if a brake cable continues to run through the gas pipe, then you are usually forced to drill new holes for the split pin attached to the pulley.
