What up H-T
So today I was at the shop doing a axle swap, and the pads and rotors looked like they need to be replaced. So I went on and replaced them both, on top of that i knew it was time to rotate the tires, so i did that as well. When I was driving home from the shop I went to press the pedal and it completely sank and i quickly pumped it but got a pulsating response. So When i got home i took the brakes apart and looked, re cleaned everything and everything looked good. I rotated the tires back to how they where and and torqued everything down and went for a test drive the pedal was firm, but know the pedal still pulsates, the steering wheel tugs alittle bit and i can't seem to find a answer... I've replaced the ball joints (3 months ago) tierods (5 months ago) Wheel bearings (1 month ago) Axles... I can't seem to find the problem... any help would be useful, Thanks!

 

i say check your rotors mite be bad. iv seen it even with new one

 

Is the pedal still spongy?

 

Barely seems pretty firm

 

If the pedal is at all soft, bleed all four wheels thoroughly.

 

Okay sounds good Ill try that and take a look at the rotors to see if their not bad off the line. and go from their

 

Did you replace the pads with OEM or parts store ones?
Also did you bed in the pads?

 

i would check rotor runout, also check runout on the hub.
one of the napa clinics i went to said brand new rotors can be also defective, or maybe warped. also have excessive runout, also sometimes rust on the hub can cause some runout, put lugunuts on the rotor and torque it to spec in criss cross pattern i believe 80ft lbs and then check runout.
i would check runout, and if the runout is excessive i would try to remove rotor and rotate it 90 degree and check again and check runout until i get the best runout.
also on the hub.

also u maybe warped it. for the pedal i would try bleed it 1st at the master then wheels, check rear wheel cyl for leaks, adj rear shoes if it has, or maybe it might be master cyl intermentent interal leak.

 

I got store brand.. the rotors have warranty so i can get them replaced, but I'm gonna take a look tomorrow and see if I can get it going with no problems before i head to the store again.. Ill keep you guys up to date with everything

 

Forgive me for asking... but when you went to drive it home, were the brakes already fully pumped? Was that the first time you went to pump the pedal on the way home? Rotors could have possibly gotten damaged from that, if you say the pulsation is still there.

 

The pedal was pumped before i turned the car on

 

bleed the lines i would say or checke the rotors
