How to Diagnose and Repair a Sticking Brake Caliper


Hello my name is aaron
and im michael
and we are auto e-clinic.
Hello and thank you for tuning in today.
what we have in the shop today
a 2005 chevrolet corvette
this is a sweet ride
but no matter how good it looks
eventually they all will break. Now on this one
we have the left front wheel
dragging
now in this case
we are certain its the brake
but we are going to tear into it remove the tire
and find out whats causing
this left front wheel or brake to drag
lets do it so we can test drive this baby.
cant wait for that test drive
we are going to open the bleeder
and see if that frees it up .
you see that we have too much drag
we are going to have to remve the caliper.
close the bleeder back up
that right there
i think thats our problem
the pin is sticking
now you see
it spins completley free now
you can see where it has been schorching
and dragging
see how its mainly concentrated at the bottom?
on both pads
that right there
will help me diagnose this
we are going to see
this slider pulls out easy
this slidewill not move
so let me get a pair of pliers and pull that slide out
now we need to rotate as we pull out to get this out
and there you see
thats why the brake was dragging
the slide just rusty and dry
not allowing any movement
there is no need to replace this slide so we are going to use the wire wheel to clean it up real good
and the we are going to lubricate it and stick it back in
now you see, nice shiny free of rust and now we are going to lube it upand stick it back in.
here is the caliper bracket off and we see no restriction now.
here is the side we had the problem with and it is still not as free as the other but we will put some anti sieze on for lube
rub that in real good and you will see
now it moves in nice and loosley
no resrictions
and that should take care of the sticking proble we have.
now we will put our bracket back on
put your brake pads back on
now brake pads
your wear indicator
always goes on the inside
ok
now as you can see the wheel spins freely
and thats how you fix a sticking brake caliper
