The invention discloses an automobile anti-ineffectiveness brake system which comprises an air compressor, an air filter, an air storage cylinder, an air delivery pipeline, a multiple-loop protective valve, a foot / hand brake mechanism, a relay valve, a spring energy-storage air chamber, a front-axle and / or back-axle brake, an anti-ineffectiveness brake main valve and an anti-ineffectiveness triple-control relay valve. By the automobile anti-ineffectiveness brake system, brake moment can be effectively compensated in time when in situations of system failure and blockage, component jamming, pressure reduction and quick leakage, and ineffectiveness of front wheels or ineffectiveness of back wheels or ineffectiveness of the complete automobile can be remedied. Further, the automobile anti-ineffectiveness brake system is convenient to mount, low in installation cost, flexible in operation, excellent in performance, and capable of effectively overcoming defects of ineffective brake, poor brake and the like in the prior art. In addition, with the automobile anti-ineffectiveness brake system, safety and reliability of the anti-ineffectiveness brake technology can be improved so that popularization and implementing of the anti-ineffectiveness brake technology are facilitated.
