My front left caliper sticks , so i replaced it with a brand new one , still does the same thing and wore out new pads within 2 months . Also rear brakes don't work at all and have good shoes . This is on a 99 4runner . Thanks

 

Front brakes - could be proportioning valve in your master cylinder malfunctioning. Also, if new caliper was a cheapie, well you can figure the rest on that one. As for your rear brakes, check the adjustment of your emergency brake cable. Yep that's what I meant, if that cable is too slack/loose, then your wheel cylinders may not be able to push the shoes out far enough make good contact. Proportioning valve may also be at work on this issue too. Take off the rear wheels and drums and have someone push on the brake pedal and see what the wheel cylinders are doing, if anything. Let us know what you find out.

 

when was the last time that you flushed your brake system because there might be some buildup in the lines and that can cause such things to happen

 

Never flushed it , i just got it a few months ago . How would I flush it , just like bleeding with brake fluid or is there other stuff to use ?

The caliper I bought was no cheapie for sure . Will try pulling the wheels and drum and see what they are doing . Thanks
