My son rides my 98 srx 600 and he lost the brakes. I checked fluid it was fine , he lost them again I changed master cylinder he lost them again I changed the line the pads the caliper bleed them them. Then I went out with him tonight and we both lost our brakes i ride a 02 srx. we ride VERY hard with heavy throttle and hard breaking. Are they just getting to hot and failing ? what can I do ? not to mention his buddy was with us with his mxz 600 and he said his were getting weak but we had nothing ???
