Default Re: 98 civic brake drag issue

Thanks Tegger for your hard work on that website and input.

So I replaced the Brake Caliper again. Got it from Partsource. I know this
is not a preferred source, but thats where the original replacement came from,
and they asked me to try this before they would refund my money.

This time, the clips and hardware that came with the caliper actually worked.
As I mentioned earlier, I figured that would be one of the biggest reasons
why the brake was hanging in the first place. Sure enough, upon disassembly
of the caliper bracket, the old clips were in very sorry shape.

Got it all installed, lubed her up as you indicated (careful not to get any
on the rotor surface or surrounding areas).

On another topic, as I indicated earlier, I have now confirmed that the front
wheel bearing is bad on the same side the caliper was dragging. Since the
caliper was defective, do you think Partsource will help me out on the
bearing? Pretty sure the reason it failed was due to heat buildup from the
bad caliper. I guess there is a margin for installation error, but is it
worth a shot?

So then I bled out the new caliper. Took it for a short spin to try some low
speed braking to check for pulling left or right, performance, all seemed
fine. Tried a couple higher speed stops, no problem.

On the highway at 80 km/h I hit the brakes pretty hard. The car suddenly
went all squirrelly on me, got away from me, and I ended up in the ditch.

So now I have other issues. I am OK by the way. The car is mostly undamaged.
It definitely needs an alignment now, along with a few suspension components.
I noticed my rear upper suspension mounts are now both loose. Will replace
those tomorrow. Here's what I checked over:

1. Both lower ball joints are under a year old. They seem fine using the
'reef on the tire while on the ground' method.

2. Both Upper ball joints - no extra play. Tried moving the steering
knuckle back and forth to test this.

3. Tie rods - no extra play. Just grabbed one and tried moving back and
forth. There is a small amount of play due to a worn steering u-joint, but
the tie rods and rack seem OK.

4. Springs all around. - no problems apparent. Visual inspection in the
areas Tegger indicated.

5. Rear upper control arms - both are shot. Once again, the 'reef on the
tire' method. LOTS of play here. They are definitely shot. The Rear Upper
arm does come with both bushings (inner and outer) so I am hoping this will
fix that.

6. Rear Lower control arms - no noticeable play. Wasn't quite sure how to
test these, but everything appeared tight.

Did I miss anything?

The car doesn't feel safe at highway speeds right now, though the steering
seems fine. I'm thinking its the play from the rear upper arms that is
causing the problem here.

So, to anybody reading this, when doing your own brake work, BE CAREFUL when
you road test your vehicle. I was EXTREMELY lucky. and probably stupid. OK
definitely stupid.

Any input on the suspension inspection is appreciated. Once the car is road
worthy, she goes in for a final inspection and alignment at the dealer.

Glad I can smile about it now.
