Front squeak

[Sailor Bob]

I've had a front end squeak for a couple of weeks - it was beginning to bug me so I did some reading and the symtoms sounded like a bad bearing. This made sense to me because I had liberally greased all bushings and checked the brakes for wear (no sweat).

Bought the parts, removed old bearings on offensive side (looked perfect) installed new and reassembled as disassembled (re service book ) . Check rotation of hub - good, installed caliper - half rotation good other half light friction. Bled brakes, installed wheel. Checked rotation - friction all the way around - what the !!!.

Just stopped raining - going for a spin.

I'm no mechanic. What do you think?

Just finished a quick run in the Z, nice blast on the highway - squeak is gone, did notice however that the hub is hot to the touch. Perhaps normal?? Would this contribute to grease breakdown and subsequent bearing failure?

Got me thinking the rotors are poor $$$. Basic solid non slotted type.

Thoughts?

Sounds like 2 things. Warped rotor, feel any pulsing in the brake pedal? 2. Sticking caliper, which would cause a warped rotor.

That's what I was thinking. Had another look, I got one pad significantly thicker than the other - I assume that means a sticking caliper piston??

My thoughts exactly. I've had the same scenario on a few different cars in the past. Quite common.
