Having problems with your Buick Grand National ?
Problem with 1987 Buick Grand National. Brake indicator light, in the dash, comes on momentarily when the petal is dipressed and the brake fulid in the master cylender, on one side, is clody and brownish in color.
Hi! The master cylinder is faulty thats why it lights up. You should replace the master cylinder to prevent further damage and accidents. Once replaced this will be gone and your brake will work perfectly. Hope this helps and have a good one!
