Un bolt master cylinder and pull forward and to side without disconnecting any lines. Get up under dash and disconnect linkage to front of booster pushrod (This can be tricky and hard on the neck and headbone). Remove vacuum check valve from booster, remove 4 nuts holding booster in place and remove unit. Installation is reverse steps.

If you remove the master cylinder first there is

Hi, the screeching noise could be a wheel bearing,if there is enough play in the bearing this could give a bigger air gap between the abs sensor and reluctor which would bring the abs/tcs lights on.

here you go...

The power brake booster is a tandem vacuum suspended unit. Some models may be equipped with a single or dual function vacuum switch which activates a brake warning light should low booster vacuum be present. Under normal operation, vacuum is present on both sides of the diaphragms. When the brakes are applied, atmospheric air is admitted to one side of the diaphragms to provide power assistance.
REMOVAL & INSTALLATION

1994-97 Models
See Figures 1 and 2

1. Apply the parking brake and block the drive wheels.
2. Remove the master cylinder-to-power brake booster nuts, then reposition the master cylinder and combination valve out of the way; if necessary, support the master cylinder on a wire to prevent damaging the brake lines.

When removing the master cylinder from the power brake booster, it is not necessary to disconnect the hydraulic lines, therefore the brake system should not have to be bled.

1. Disconnect the vacuum hose from the power brake booster.

Fig. Fig 1: Common power brake booster attachment

1. From under the dash, remove the retainer and washer from the brake pedal on 1994 utility models. On all other models, remove the retainer and brake switch from the brake pedal.
2. Disconnect the pushrod from the brake pedal.
3. From under the dash, remove the power brake booster-to-cowl retaining nuts.
4. Back under the hood, remove the power brake booster and the gasket from the cowl.

To install:

1. Position the booster to the cowl using a new gasket.
2. Install the bo oster retaining nuts and tighten to 16 ft. lbs. (22 Nm) 1994 utility models, 24 ft. lbs. (32 Nm) on 1994 pick-up models and 27 ft. lbs. (36 Nm) on all 1995-97 models.
3. Connect the pedal pushrod and install the washer or switch and the retainer.

Fig. Fig. 2: Checking the piston booster rod using the gauge tool

1. For all vehicles cover ed in this guide, gauge the booster rod:
   1. Apply 25 in. Hg (85 kPa) of vacuum using a hand held vacuum pump or apply maximum engine vacuum.
   2. Chec k the maximum and minimum rod lengths using J-37839 or an equivalent pushrod height gauge.
   3. If the piston is not within limits, install a service adjustable piston rod and adjust it to the correct length.
2. Reposition the master cylinder and combination valve bracket to the booster studs, then secure using the retaining nuts. For details, please refer to the master cylinder procedure located earlier in this section.
3. Start and run the engine, then check for proper booster operation.

Remove the rod going to the brake pedal,then remove the master cylinder,you may can unbolt the master,from the booster,and move it out of the way without removing the brake lines,they will give quit a bit.Now go back inside and remove the four nuts on the studs holding the brake booster in,they may be a little hard to reach,and of course remove the check valve with the hose on it,going to the booster under the hood,If this was at all helpful,please rate,thank you.

1. Step 1 Mark the brake lines coming into and out of the master cylinder using masking tape and permanent marker.

Let me know if this helped....

I would suggest before thinking the motor is bad that the tracks that the window run in need a good cleaning.
I bought 97 Olds a couple of years ago and had the same problem - after cleaning the gunk - I figured it was a soft drink of some flavor got spilled in the door - and lubing the regulator gears and joints with pure silicone spray ( don't use any product like WD40 as they are oil based and will attract dust ) it worked like new. If you need to replace the motor YES it can be done at home but give yourself plenty of time, it can be done but you won't do it in an hour

it's not worth the headache,if you are doing it yourself. If you are going to pay someone just go to your local keyless place,you will be alot more happy than the trouble you will go thru the other way.
