Last night, I noticed that my brakes are spongier than usual... I have to depress the brake pedal almost 1/2 to 3/5ths of the way down to remain at a complete stop during the first application of the brakes. The pedal does not sink to the ground, but a higher than normal pressure is needed to maintain stop.
If I quick let go and re apply the brake, I don't have to push down as far, and the brakes feel firmer. Also, when applying a hard brake for the first time in a while when driving, the truck kind of leans to one side like the brakes are not being applied evenly. The dealer told me I need a new master cylinder ($540 installed) which does not sound right. At 110,000 miles, I have no reason to believe this is true. My oil was changed last week, and one of their procedures is to check the brake fluid level. is it possible that air or water has gotten into the brake fluid causing this?
