Brakes bad even after replacing pads/rotors

Front brakes were good. Back brakes were horrible. New pads and rotors. Was full of fluid, no leaks. But even with new pads and rotors, pedal all the way to the floor.

You need to replace the master cylinder. If all else is good and the petal goes to the floor, that's really about all it could be.

Why squeaky brakes on jeep


front or rear.??? my guess front.... wild guess.
if car has pads with the noise makers this is normal and the early warning.
if pads are thick (why not look first???) and squeal.?
  1. this is normal all disc brakes squeal, can and will if they want to.
  2. or has missing anti-squeal shims on pad due bad mech. serv.
  3. or not using anti-squeal glue on back side of new pads.
  4. if in a perfect world they can in fact squeal.
if you have new rotors and pads and all above is good. they may not squeal. the rotors can be tad bump and the pads will resonate to this rotor surface, its harmless this. only annoying.

other factors, why not do a full inspection of the pads and rotors
first and not just guess and wonder.
like:
OMG:
  • Cracked rotors
  • leaking DOT 3/4
  • calipers guide pins seized.
  • Pads shot
  • missing parts, the FSM shows all parts as does jeep parts page.
  • rotors shot , worn illegally thin, warped, or just ugly bad and old.
this is what we call SOP
standard operatiing proceedures.

I have changed the rear rotors and brake pads, bled the brakes after putting itall back together. Seemed to have brakes but then shortly thereafter they are like a sponge. Last time I tried bleeding them...


Hi, bleeding your rear brakes with engine running, you should get enough pressure out of the lines to squirt 3-4 feet. In other words, good pressure. If all you get is a trickle, you probably have a bad master cylinder. Just because its full of fluid, does not mean the seals arent shot. If you have bled them in order, left rear,right rear,left front,right fornt and have bled them enough to get fresh fluid out of each one without achieving good solid pressure at all wheels, replace your master cylinder. There is a proportioning valve, but usually it will affect only one wheel when going out, usually the left rear.
Brake pedal height comes from the rear brakes, so if you have bad pressure there, you will never get a good pedal. Eventually with a bad master, your brakes will go completly out..Mike

SOUNDS LIKE ITS THE FRONT BRAKE GRINDING 3TO5 MPH YOU CAN FEEL IT GRINDING ALMOST LOCKING UP I LOOKED THROUGH THE RIMS AT THE ROTOR IT DOESNT LOOK BAD.COULD THE STRUTS BE TO BLAME CAUSE I PLAN ON...


If the brakes are grinding 3 to 5 mph, and you feel it, the rotors may not look bad, yet, but the pads may be worn down. I don't think the struts have anything to do with grinding. Struts have to do with the bouncing up and down of the front end when going over bumps.

Good luck on this repair.

Brakes are going to the floor most of the way checked rear brakes and they are still good bleed them and problem still there


Normally when the brake pedal goes almos to the floor it is an indication of low brake fluid. Low brake fluid is an indication that front and/or rear brakes are wearing. As the brake pads wear down more brake fluid will be required in the wheel cylinders or calipers. Hint, the front brakes usually wear much faster than the rear due to the fact that the fronts due a much greater braking function that the rear. Check the front pads. Don't let them get down to the metal scraping metal stage before you change them out. This causes unnessary damage to the rotors. Look at your master cylinder on the firewall under the hood in front of the steering wheel. If the fluid level is belowhte "max" mark add fluid. Low fliud should also show as a red "brake" light on your dash, but not always.

Where do you put the brake fluid on this car? Because, my car is making a grinding sound when I put my foot on the brake.


The grinding noise probably means you need to put new brakes on. If you fill the brake fluid reservoir, and then change the brakes, the new fluid will run out anyways, because the new brakes will have to be put in, and the fluid will run out.

1990 Toyota Corolla rear drums bad?


If your pads are completely gone then you may have damaged the drums if you still have any pads left or shoes if they are drum brakes then you still need to have your drums checked out for the proper size to still be there for the brakes to function properly. You won't know until you look at them or are shown them by a pro. who has measured and found them to be beyond reuse! If you had leaks then you will need to repair the brake calipers or the wheel cylinders depending on which system you have drum or disc they are different!!! Hope this helps someway !!

2005 Dodge Durango Front Brake Squeal


Did you buy factory pads or get cheap aftermarket pads? If aftermarket did you get the ceramic? The cheap aftermarket ones tend to squeal pretty bad. Like the last comment on here, you should have your rotors turned whenever you change the pads.

Front brake pads for 1997 ford ecscort encore


The binding of the brakes is causing the pads to overheat, which is causing the smoke. You need pull the wheel and check things out. Your caliper must be bad (not releasing). You need to replace the caliper, brake pads, and have the rotor cut (a full service parts store or shop cuts the rotor perfectly smooth on both sides), or replaced (it may be cheaper to just buy a new rotor). You should also always change the pads (and check everything else) on the opposite side. So, if u do the brakes on the driver side front, always do the front pass. side at the same time, likewise if u do rear brakes.
Whenever you do brakes u should also flush out the brake lines (by bleeding the brakes) until the brake fluid flows absolutely clear. Old brake fluid is the #1 reason for caliper failure. I've seen many times people replace brake components w/out changing the brake fluid, only to have the brakes wear out very quickly, or not function properly. good luck! hope this helps> please rate this!couontrycurt0

300zx front brakes.


Nothing more special than a basic metric socket set, a good size C-clamp, and maybe a screwdriver. Remove the wheel and unbolt the caliper from the hub (two bolts on the backside, I believe 17mm). Remove the brake fluid reservoir cap. Slide the caliper off the rotor and remove the outer pad. Use the C-clamp against the inner pad to compress the pistons back into the caliper to provide clearance for the new, thicker pads to clear the rotor. Do the same for the outer pistons. Install the new pads, remount the caliper, and put the wheel back on. Replace the fluid cap, pump up the brake pedal for pressure, then take it out and bed the pads in with several back to back stops from 30mph with steady, even pressure on the pedal. You'll be good to go at that point.
