Brake block holder of high friction coefficient brake block and brake device

The invention discloses a brake block holder of a high friction coefficient brake block and a brake device, wherein the brake block holder of the high friction coefficient brake block comprises a support body which comprises a support body end part and a support body middle part; the width of the support body end part is smaller than the width of the middle part of the support body so that a brake block holder block is formed between the support body end part and the support body middle part. The brake block holder of the high friction coefficient brake block and the brake device provided by the invention can be clearly different from the brake block holder of the low friction coefficient brake block in appearance in the prior art by changing the width of the support body end part; the brake block holder effectively prevents dislocation of the high friction coefficient brake block and the low friction coefficient brake block, thereby improving the safety of driving process.
