What to do if your car has excessive pedal travel?
If you don’t typically engage your parking brake, the parking brake can be key in figuring out if your car is suffering from excessive brake pedal travel. If the parking brake doesn’t properly engage, that generally means a low pedal. 3. Bleed the Brakes.
Why do I have excessive brake pedal travel?
Excessive brake pedal travel happens when you feel your pedal sinking rapidly while braking, or sitting lower than usual when activating your vehicle’s brakes. This can happen due to wobbly discs knocking pistons back or air in the braking system. Performing DIY brake repair to fix excessive brake pedal travel can be a tedious task.

What Is Excessive Brake Pedal Travel? Excessive brake pedal travel happens when you feel your pedal sinking rapidly while braking, or sitting lower than usual when activating your vehicle’s brakes. This can happen due to wobbly discs knocking pistons back or air in the braking system.
What to do about long brake pedal travel after pad change?
Try bleeding them. And check how much free play you have on the brake pedal. You should have about ¼” or so. This can be adjusted quite easily at the master cylinder/brake pedal pushrod. I had this same problem on an Astra after a front pad change.

Why does the pedal travel less than the caliper?
The area of the piston in the master cylinder is less than that of the brake caliper. This reduces pedal effort but increases travel. The greater the difference in the piston sizes, the more multiplication of force and the increase in travel. Since a single piston is moving two caliper pistons, pedal travel in doubled.
