Has anyone experienced lose of brakes or a spongy pedal? I had this happen a couple times on recent trip to Hatfield and yesterday when I was playing around my house. It ONLY happens at slow speed AND extreme angles. It has never done it just driving down the trail at a normal speed or going up or down a hill. It acts exactly like there is air in the system. The pedal goes to the floor, pump it up a couple times, and pedal pressure returns. I have tried bleeding the brakes and got no air out of the system and the master cylinder is full. Any ideas?
