Brake problems

id bleed the brakes and if that doesnt solve the problem then its probably a bad caliper. is there fluid under ur car after u park it?? if you havent checked for it, then i would check for fluid. cause there may be a leak. good luck

bleed them anyhow. the fluid is hygroscopic (has an affinity for water). flush them to clean up fluid and remove any air. a mitivac is great for doin this.

also, have you noticed any fluid under the master cylinder (like a trail goin down the brake booster). normally, with a good closed brake system, new brakes are on, and the fluid level is full. brakes wear, level goes down. if you dont add anything, when you do the brakes, as you just did, the level goes back up near full (minus a little amount for rear pad/shoe wear, which is normally minimal). do you have to add fluid to it ever? if so, really check the lines and calipers (as mentioned), and esp the master cylinder. a bad MC seal can lead to loss of fluid and spongey, slow brakes. also, if braking improves when you pump the brakes a couple of times, look further. in any case, fix it. you dont want to operate with barely marginal brakes. one more iota of diminishment could be very bad. good luck.

If you pump the brakes and the pedal doesn't get any higher than there is no air in the system. If you pump them and they come up, they need to be bled. Also check the condition of the rear brakes. Are they adjusted properly? Rear brakes that are out of adjustment will cause a low brake pedal.
