TECH TIPS
FUNCTION
Air brake hardware kits are designed to provide all the components required to achieve maximum lining life, stopping
power, and stability of the foundation brake at each reline. Each hardware kit is designed for a specific application;
correct component identification is critical. Euclid Master Catalog 100 provides critical dimensions of all components
for identification purposes. Wall charts are also provided to aid in brake shoe identification.
TYPE
In the aftermarket, air brake hardware kits are available in various quality levels and number of components in each kit.
The end user should pay attention to these differences to assure that he is purchasing a quality kit from a reputable
manufacturer. The old saying, "You get what you pay for," certainly applies to brake kits.
Euclid air brake hardware kits are available with a variety of components, from minor kits which range from some
containing only high wear components, to the major kits which repair one complete wheel. These major repair kits are
Euclid's MEGA PLUS Maximum Life, MEGA Premium Quality, and STOPMATE Standard Quality brake kits. Euclid
MEGA PLUS kits are complete kits designed for today's "extended service" applications and provide for maximum life
by using heavy-duty shot-peened return springs, dimpled anchor pin bushings and antiseize lubricant. Euclid MEGA
heavy-duty brake kits include all the needed components including: anchor pins, rollers, heavy duty return springs,
spring and roller retainers, washers, lock rings, and bushings. Euclid STOPMATE brake kits also include all the
components needed to repair one complete wheel, but offer a standard quality level rather than a premium quality
level with added durability. In this issue of Tech Tips we will highlight most of these components, their wear points,
and types available.
GENERAL INSPECTION RECOMMENDATIONS
As foundation brake hardware wears, brake shoe and lining wear is affected. Brake lining wear patterns are a good place
to start troubleshooting foundation brake hardware problems. Euclid supplies a Wall Chart (A-504) and a Service
Bulletin (B-20) which describes possible causes and solutions to the most common brake lining wear problems.
BRAKE SHOES
Brake shoes need to be inspected for anchor pin connection wear (See Figure 1), roller connection wear, web
straightness (See Figure 2), stretch (See Figure 3), and table flatness. Several styles of tools to check these wear points
are available individually or as one unit such as Euclid’s E-3863 Brake Shoe Gauge. Most brake shoe gauges are "GO/
NO-GO" style and reject only those brake shoes which are worn beyond the minimum allowable dimensions. To achieve
the best brake performance, old worn shoes must be discarded and replaced with new lined shoes.
