As the title says, when i step on my brakes my headlights dim, interior lights dim and my blower motor slows for second. i already know i should check my battery and alternator but I have heard of a lot of people having this problem and no one seems to ever find the solution. everything i have read the people just end up trading the car in or scrapping it. So, any ideas?

Have the battery and the Alt tested . also make sure all connectios and grounds are clean. A "big 3" upgrade helps too
