When bleeding the brakes on a 1989 olds cutlass ciera where do you start first and how do you use the tool to do the job

You always start the farthest from the reservoir, pass. side rear – dr. side rear – pass. side front – dr. side front. On each wheel is a slave cylinder that operates the brakes. On the back side is a zerk fitting, You must find a box end wrench that properly fits the zerk or bleeder valve. You can purchace a self bleeder tool, or use too people to bleed the brake system . Fill the reservoir one person pump the brake petal several times and hold pressure on the petal, while the 2nd person loosens the zerk fitting realeasing the pressure from the slave cylinder on that wheel, then tighten the fitting and repeat until only fluid comes out no air. Fill reservoir and move to the next wheel. Do all four wheels in this fashion, ALWAYS keep the fluid full, if you let the fluid get low it will suck air into the system an you’ll have to start all over again.
