Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. Did you still need help? Are you looking for some possible causes?
Ok no problem. One thing that we see a lot at causing this problem is bad calipers. Sometimes the top or bottom caliper pin sticks causing the caliper to bend when stepping on the brake pedal. This will cause it to flex causing excessive amount of brake pedal travel. Sometimes just replace the calipers will simply do the trick.
Also, if any of the front calipers are loose, it can and will cause the brake rotor to move and flex back and forth when stepping on the brake pedal so be sure to check that too and replace any loose wheel bearings as needed.
If needed, you can clamp off all 4 brake lines or hoses, start the engine and check the brake pedal. If it is nice and firm, then disconnect a clamp from the brake lines one by one until the brake pedal goes back to soft as this will help you pinpoint which brake set up the problem is in.
