Brake symptom question

[Trdsupranick]

Hey All,

I recently replaced my front rotors, pads, calipers. I bled lines etc.. stopping is good and strong..no noise either but for some reason I feel like I have to press hard on the brake pedal.

It does not have a squishy feeling like you would have if air was in the lines and remember I did bleed all four lines correctly. Reservoir brake fluid is at the appropriate level too. It really feels like I have to put more pressure on the pedal still.

I have not changed my rotors or pads in the rear yet although they weren't too bad though they need to be changed soon....does anyone have an idea

Do you think it means the rear pads need changed?? Any ideas??

Did you use any components that were not Toyota OEM? Did you bleed the rear brakes as well?

I also have hard brake pedal. I thought all 4runners are like that. I also replaced all brake pads and one of front calipers, stayed same hard. But I did not bleed rear brakes, just fron one which had caliper replaced. Overall I am not too happy with 4runner brakes.

Those pads appear to be the ceramic type. I haven't played with this type as of yet, but I recall semi-metallic pads used to have a much higher pedal effort than organic types did, although they more than made up for it in fade resistance.

A quick googling of the topic listed a few results that suggest that some brands of ceramics do have a high pedal effort.

Another possibility is a partially seized caliper; does it pull to either side when stopping?

I replaced the calipers they are new..because they both seized lol.....there isn't any pulling and the stopping is great...it just seems that I have to increase the pedal effort.

The brand of pads I bought are called Adaptive Ones. I still need to put new pads on my rears I am hoping that is really the case but you made a good point about the materials in the pads. I know that these adaptive ones are a new type so you could be right that i will be increasing my pedal pressure.
thanks for the info!
