I just installed the BAT brake kit ($175) and except for a couple of rusted torx bolts on one of the rear calipers everything went pretty well.... However, when I was installing the fronts and compressing the front caliper (to install pads), some brake fluid leaked backed out of the brake fluid reservoir. Pedal seems kind of low now, and brakes seem kind of weak in terms of stopping power..... I ran out of time(those rusted bolts on the rear took quite a bit of time), and skipped bleeding the lines since I didn't disconnect them from the calipers....
.... My question is: Is it normal for brake fluid to leak back out of the reservoir? Could air have entered the system? Could there be any other reason for my decreased brake performance?
Thanks for everybody's help!
