i have a 98 gmc jimmy i'm assuming its going to b the same on a blazer but how do u bleed the brakes?

 

Have a helper pump the pedal 3-4 times, then start at the RR, and open the bleeder. Close it when the fluid stops flowing, and repeat. Do this until all the air is out, or you have clear clean fluid comming out. Then move onto the LR, RF, LR. Good luck.

 

Yeah, its best to start with the furthest one from the master cylinder (RR, LR, RF, LF).

 

Don't forget to keep the master full of fluid. You let it get dry and you'll have to bleed the master as well.

 

Also if the master gets empty youll get air in the system so youd have to bleed them again anyways. so yeah, keep it full.
