So awhile back my brake lines gave out due to corrosion. I had them all replaced along with 2 new front calipers. I get it back and start tearing the interior out to rhinoline it. I notice for some odd reason my e-brake bracket it leaning to the right a little. Stupid as I am I hammer it back to the left. When all said and done I notice my brake light on. With the advice of members here I checked the grounds and it still came on intermitently. I brought it back to the mechanic (very trusted) and he told me a day later it was fixed. Drive it home no problems. Its been sitting a week and I drive it today. I start it up and the brake light is very dim. Brakes feel fine like before. Drive it around it gets brighter and goes out and pops back on again. I was forced to slam on my brakes and the light went out. Stopped at a stop sign and it was bright again. Any ideas? Could their be less power/pressure in the line cause they are new / maybe bigger / or longer. Is their such things as a brake booster that I can put in it? My main concern is that my son rides in it sometimes. I don't want the brakes failing when he's in it. Thanks in advance for the help.
