i have recently upgraded my brakes from standard corona solid discs to fully vented all-round. I put ma61 rears on the back and RA65 vented brake setup on the front. After changing the brakes over i have been experiencing lockups on the front left and with a little bit more pressure the front right also locks up. I'm worried because it doesn't take much to get the wheel locked up which drastically effects the braking quality. can anyone tell me what may be causing the problem, cause after the past few rainy days i have been getting a lil bit scared to drive.
