Hello. Was the pedal going all the way to the floor before all the work was performed?
ok. Was it exactly like this before all the work? Or did this low pedal issue begin after the work was done?
OK. it looks like the problem is in the front. First, check to make sure that the calipers are not reversed by making sure that the bleeder screws are on the top of the caliper and not on the bottom. Second, when you replaced the front pads, did the pads look like they had worn evenly? or were they slightly wedge shaped?
Since they were worn unevenly, that usually means that the caliper slide pins are not moving freely. If they aren't moving freely, the pads will not sit as close to the rotor as they should, so when you apply the brakes the pads have further to travel before contacting the rotor. That will result in excessive brake pedal travel, and uneven brake pad wear.
did you replace the caliper brackets and slide pins as well?
Sorry, you are correct. The caliper bolts to the knuckle. And, if you clamp either of the front brake hoses, the pedal is hard and normal?
Ok, have you had someone apply the brakes, and visually inspect the calipers to make sure that they aren't kicking crooked or anything?
Considering everything checks out, and all parts including hoses are new, I am a total loss at the moment. I will open this up in case someone else has any ideas. someone else should be with you shortly.
real quick. you have tried this with the wheels installed, correct?
OK. Just as long as the rotor was tight to the hub.
does the pedal go to the floor when the engine is off? or only when the engine is running?
when the engine is off, the pedal is normal?
are you absolutely certain that what your experiencing is not normal? Have you tried driving the jeep and see how it actually feels when in real use? ( sorry if that's an insulting question) I have had people bring in nearly new cars with a similar complaint and the brakes are actually perfectly fine.
ok, and when you step hard on the brakes, the pedal goes to the floor, and the truck doesn't come to a stop as it should? or the pedal gets hard?
I would conclude a potential problem with the booster, but considering that the problem goes away with the front hoses clamped off, ill eliminate that as a potential cause. Sit tight and if someone else knows what's happening, they will reply right here. Sorry I was unable to help you get the problem resolved.
Hi Im David. bleed the brakes with the engine running. bleed them again and again and again. it took me at least 8-11 times of bleeding brake on a few of those over the last couple years.
and you're geting straight fluid out of all calipers?
get another master cylinder.
make sure you bench bleed it before installing.
ill opt out now, but thats my advice.
Different expert here.
Did you still need help?
Would you like a test to help pinpoint the problem?
Ok, one minute..
You are going to have to pin point what is causing the spongy pedal. This is done by clamping off all four brake lines at the hoses by each wheel. Start the vehicle up and check the pedal. Chances are that it is nice and firm. If it is not, the master cylinder is at fault and will need to be replaced (or there is simply air in the system). If the brake pedal is nice and firm, when doing this, then disconnect the clamps one by one and see what makes the most difference or which one allows the brake pedal to sink when releasing the clamp.
Ok, then the problem is in the front calipers then. Check to be sure they are not bending or flexing when the brake pedal is depressed.
It could be faulty calipers, installation problem, or even loose wheel bearings. Be sure the rotor and wheel bearings are not bending and or flexing when the brake are applied.
If the brake pedal goes to the floor or close to, when stepping on the brakes, everything is not working properly. Something is being overlooked.
what about having the abs module bled?
