Exhibit A—Recommended Prctices on Brake Brake Beam Reclamation and Repairs The reclaiming and repairing of brake beams should becentralized at some convenient place, where there is suitableequipment for doing the work in an economical and safemanner. General Inspection All defective brake beams that are received at a reclaim-ing plant should be completely dismantled. After brakebeam has been dismantled the various parts should be sepa-rated and given a general inspection. Any part of the brakebeam that has any of the following defects should bescrapped: Excessive deterioration due to rusting or longlife; undue wear; broken or cracked. The following practices should not be permitted: Build-ing up any part of the brake beam by gas or electric welding;straightening of the strut or brake head by excessive heating;any parts of brake head or strut that cannot be straightene
