i have an 86st did five lug conversion & front disk was one inch bigger it also upgraded me to disk on rear never got the rear breaks to work properly have checked to see if there was any difference in break master cylinder from the st & the gt no difference is there something in line that changes the presure from drums cause it seams like the calipers are frozen but there not just dont think there getting enough fluid pressure..also does any one know where to get some good drilled rotors front & rear & whats the price range any help would be great
gt and st are both the same. front disk rear drum. check to see if the master matches a gt-s which is 4 wheel disk.
agreed with jwagner! the ST and GT is the exact same set up (4 bolt + rear drum) so you have to check a GT-S!
you have to change out the master to get the right ratio for the brakes......drums dont take as much pressure to use but calipers do........
