rotor, pads, brake hose issue

[floyd756]

hi, i just purchased my second toyota recently,

i got it serviced by toyota and took it from perth via broome

to darwin and further down to brisbane. before i took off toyota said my brake

pads needed replacing soonish as well as my rotors need turning. in brisbane

i orderer new pads and rotors and finally got around to swap them today.

drivers side was quickly done. on the passenger side i noticed that my brake hose is squeezed together

to a point where there cant be much (if any) fluid traveling through it.

i swapped the rotor and started the pads. when pushing back the cylinders i struggled at the bottom right one (i guess due to the blockage) i opened the bolt to allow some fluid to be pushed back. i placed the caliper on the rotor and spun it. the rotor spins 3/4 and starts grinding on the wall of the caliper. it's like the new rotor is extremely warped. but it cant be, right!? any idea on what's going on?

Make sure you thoroughly clean any rust off the hubs before putting the rotors on and put a couple of wheel nuts on. Also, replace that hose.

hi trent, thanks for the quick reply. i cleaned both hubs with a wire brush and brake cleaner. i had 2 nuts on the rotor when testing.

Is there any chance my hubs are damaged? i seriously can not understand what's causing it...

Photos and videos help. But double check the caliper is mounted correctly, the pads and guides are installed correctly and that the rotor hasn't kicked. Also try loosening the nuts that are currently on and put all on and tightern them evenly.

Hubs unlikely to be damaged unless you have had a large impact.

ok, i'll take some photos tomorrow. im sure the caliper is on properly. what do you mean by the rotor hasn't kicked?

[trentmeyer23]

If you tighten one of the wheel nuts completely before putting the second on, it may kick and not be parallel with the hub, which can jam the rotor. You can also check by putting the wheel on and tightening correctly as well.

I would be very surprised if your new rotors are warped.

[floyd756]

ok, got it. i'll make sure they are not kicked. im still stunned / confused about the damaged brake line and whether or not it has anything to do with it. will upload a picture tomorrow. thanks

quick update : that's what my brake line looks like. any idea on what the heck caused that?

[trentmeyer23]

It has been hit by something, possibly a rock or stick. Not sure how much off-road stuff you do, but that is pretty common. Definitely needs replacing. That caliper is pretty much useless as is.

test rotor for warp by sitting it on a piece of glass pane. try and wobble it from all primary directions, both sides. run feeler gauge around edge to detect gap. any wobble or gaps indicate warp, or uneven glass. pane glass is generally flat enough for this test. rotate and if gap moves with rotation, then the rotor is warped. Check rotor for minimum thickness, AND even wear if ventilated, as a collapsed rotor ain't fun. I have only seen one so far.
