90 240 rear brakes! help!!!!!!!

[pktj21]

i have a 1990 240sx and the left rear slider pin for the brake caliper is stuck. it will not come out it just wont. i dont know what to do, the other comes right out. and its causing the rotor to overheat, one broke already (as i posted earlier) not both left and right rotors are discolored blue from heat, why would the right start f-ing up now? well i found 3 240's a90 and 2 93's i am going to get the caliper brackets and caliper for the rear but if the 90 parts are allready gone could i use the 93's. on my 90 model

89/90 is the same as 91-93

the pins have to be heavily greased or they wont work. to have the pin frozen, means that they had not been greased in years . better check all your wheels.
