Every 3 or 4 months my brake fluid will be just below full ,and the light will go on and off till I put fluid back up to full

You probably have a slow leak somewhere. Look for brake fluid leaks at the master cylinder and at the calipers. If you have rear drum brakes you will need to pull the drums to inspect the brake cylinders.

Small slow leaks can all of a sudden become large leaks....result....crash boom. Have a full brake inspection performed. Get back to us and let us know the result.

Thanks I'll have it checked out

If you like the car and plan on keeping it you might want to go ahead and replace all the wheel cylinders and the master cylinder rather than fixing it piecemeal.

Thanks and your right I'm disabled so do want to break down , I only drive car about 50 miles a month but I'll take to a mechanic and hold my breath LOL

Good choice. Let us know the ultimate outcome.

Octavia.....give us the good news first.
