Description
Brake shoes Newfren prorace model with racing compound for Piaggio:- Rear only for Sprint GL GT GTR RALLY TS
- Wasp PX
- Vespa PK (excluding PK S 1st series without arrows)
BRAKESHOES PRORACE NEWFREN:
The new line of brake shoes called PRORACE has been designed to add performance and exclusivity to a more than tested product. The jaw cover is made of die-cast with a special aluminum alloy in compliance with the EN 1676: 2010 standards. The braking friction material instead has a new compound with exceptional characteristics, offers considerable advantages in terms of braking, improves safety in city traffic thanks to the properties of high resistance to fatigue and stress for continuous braking and restarting during the use. Particularly suitable for racing use in competitions with scooters, it reduces braking distances and withstands heavy stress even in conditions of repeated braking at high speed. This new compound allows to obtain 30% more friction coefficient and 25% less braking distance.
FEATURES
Type Drum brake
Position in the vehicle front / rear
Particularity Racing compound
The jaws are made of metal elements in the shape of a crescent, on the surface of which there are the pads.
In the drum brake mechanism with two control cylinders, the useful action of the work is increased thanks to the rotation of the drum itself during the movement of the vehicle, which at the moment of braking tends to tighten itself more against it. As a result, the force required on the brake lever or pedal is reduced. Thus, for the rider of the motorcycle, a light pressure on the pedal or the brake lever is enough to make the shoes touch the drum, after which this effect begins to work as a sort of "amplifier".
Brake drums deteriorate very slowly and do not need frequent turning. But unfortunately the brake pads are not eternal spare parts because they are subject to wear. So, if you need to replace them, it is not necessary to take the vehicle to the mechanic, you can buy them and replace them in full autonomy. The best purchase would be through our online shop. You will save not only money, but also time.
Defects of the brake shoes
- excessive wear or damage to the logs;
- cracking of the friction surface of the block;
- deep scratches on the log seals;
- irregular wear of the logs;
- deformation.
Symptoms of brake shoe failure
- significant deterioration in braking performance;
- increase in the braking distance of the motorcycle;
- thump or screech during braking;
- violation of the vehicle trajectory during braking;
- beat or vibration during braking;
- unstable operation of the brakes;
- appearance on the stump of a protruding edge made of friction material.
Causes of brake shoe failure
- wear of the brake drum;
- increase in the interval between the block and the brake drum;
- foreign bodies or dirt on the friction linings;
- oil on the surface of the stump;
- aggressive driving style;
- use of poor quality components and wear materials;
- defective brake cylinders;
- incorrect installation of brake shoes;
- installation of incompatible components.
Diagnosis
To carry out the diagnosis independently, it is necessary to measure the thickness and analyze the external condition of the brake shoes. The minimum permissible thickness of the gasket is 2 mm. The surface of the log should be flat, with no deformation or cracks. In addition, the state of wear must be uniform.
Furthermore, it may be useful to perform the braking analysis. To do this, you need to accelerate to 60-80 km / h, driving on a flat and dry road, and brake. Under normal conditions, the braking path must be straight. Another positive sign in this sense is the lack of screeching. The complete inspection of the brake shoes should be performed at a technical service station every 10.000-15.000 km traveled.
Repair and replacement of brake shoes
The repair of the stumps is no longer considered in recent years.
The replacement of the jaws is a rather complicated and important process, which is why it is recommended to carry out the replacement with great care and attention. It is also highly not recommended to exceed the deadlines set for this mechanism. The brake shoes must be replaced every 15.000-20.000 km of travel, but in some cases even earlier (depending on the driving style).
Designed and patented in the 80s, the FTR brake shoes are particularly suitable for off-road use and offer excellent performance especially in critical conditions. The special grooves of the friction material favor the escape of water and any other sediments (earth, sand ). Furthermore, these slits on the block allow a greater and faster cooling of the friction material. They continue to be highly appreciated by users for the global stability they guarantee in all conditions of use.
