You put brake fluid in a 1990 BMD 525i in the brake fluid reservoir. This is more than likely located on the master cylinder of your braking system, under the hood of the car.

To add brake fluid in a 1990 Mazda Protege, you need to locate the brake fluid reservoir and check the levels. The reservoir is located on the master cylinder for the brakes.
The master cylinder contains the reservoir for the brake fluid. This is where you would add it on an 1990 Cutlass Supreme.
the manual trans fluid runs from the brake fluid i had a 1990 Honda ef hatch an i had to fill the brake fluid an it shifted koo after that. Brake fluid operates the clutch. Do not put brake fluid into the standard transmission.

Low brake fluid in master cylinder? Parking brake not fully released?
Loss of fluid is the typical reason, Master Cylnder failure is another. Brake failure is very typical in these vehicles...there was a lawsuit against GM in the 90's to reimburse owners.
Check your brake fluid level in your brake master cylinder in the engine compartment and see if it is down.
Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
