My wife brought her 2002 Lancer Mitsubishi car into a franchise tire &
brake shop back in April and got some new tires and a wheel alignment.
A couple of months later I was driving her car on the freeway and I felt
it pulling hard to the right. I wasn't happy with the alignment.

When she braked, at the end of June, there was a squeek sound so she
took it back to the same shop. I wasn't too happy about that, but it's
her car. Her car has about 90K miles and I think this may be the first
time they've needed service.

After they did the brake job they told us it takes about 1000 miles to
break the brakes in so it might be tight and there might be noises but
everything would be cook.

Two days later, after the first time they did the brake job, we drove
120 miles. On the driver side there was a squeeking sound. By the end
of the drive I was tired of hearing the continual squeel and squeek. It
was kind of loud.

So we took it back in and they put on new pads. The guy that did the
first job said the had put on the wrong sized pad on the first run. The
squeek/squeel went away but we inherited the "crunching" sound when we
braked.

We took it back again to get rid of the crunch sound. Supposedly fixed.
Not really tho. So today we took it back in. Just got a call from
the mgr that they did a complete brake job, rotors turned, new pads, the
works. But he said the sound was still there. One of the guys there
thought it might be the drive train.

This car ran perfectly, except for the initial squeeking that prompted
her to bring the car in, prior to bringing it to the shop.

The sound only occurs when braking. The sound is similar to the sound
you'd expect if you stopped a metal object and the stuff in the back all
slid forward to the front. A crunching or grinding sound. We can get
the sound by just going a few mph and then stopping.

I went to google and searched for Lancer Mitusbish 2002 Brakes and got a
site with TSBs. There was this one but I don't know what it means.
"2002 Mitsubishi LANCER 02 - Hydraulic Brake > SERVICE BRAKES,
HYDRAULIC [Part 030000 ]
TSB No: 0335003 NHTSA ID: , November 01, 2003 : Replacement:
Summary: clicking, squealing, or groaning noise when braking. *ph"

Any ideas what could be causing the sound? I'd sure like to get this fixed.

Try a different brand of brake pad. Some are quieter than others.

"Most" independent and franchise shops perform
FREE brake inspections. Go get another point of
view. Don't complain about the other shop, jest let
them know what the problem is..go for a ride with the
Tech so he can hear what YOU're hearing. Explain
the squeal was the reason for having the first brake
job, but now after returning 3 or 4 times, you're willing
to absorb ANY cost to have THIS symptom rectified.
DO NOT LAMBAST THE OTHER SHOP !!!
Don't go in giving the impression you're "one of those"
that can't be satisified, jest be nice, get your FREE
second opinion.


or........

tell me to kissyerass and that I didn't directly address
your question......and I'll GUESS......jest like everyone
else if fix'n to do, I don't mind at all.

Matter of fact..here...let me have the first guess aye......

Hub bearings.

there...no charge!!
