Question about Rear Brakes.....2005 Mercury Montego


Recommended Posts

We bought the car new. It has been a wonderful family vehicle. Roomy and econimical (29.5 MPG on recent 4600 mile trip to S Dakota and back, Computed by miles driven and fuel used....not the car's computer). No problems with car really. The 6 speed Aisin auto works amazingly well. I even think performance adequate with the 3.0 DOHC V6 ....considering the fuel economy.

 

But one kinda nagging issue....The rear brakes. The rears were replaced at 28,000 under warranty......rapid wear.....something about pads exposed to excessive moisture, causing them to drag against rotors, etc.

 

Now at 68,000 miles..... rear brake pads almost worn out again. And the original front pads still good. We are easy on brakes. Do you think maybe the replacement pads at 28,000 miles were somehow exposed to moisture also? LOL

 

IMHO the braking on this car, perhaps a proportioning valve or something, puts more braking on rear than normal. You can feel the rears slow to release sometimes also. I believe this is an engineering flaw, and one they won't admit to. Causing me maintenance issues I should not have. And hey....I understand brakes are a wear item.....but going thru at least of 2 or more sets of rear pads for one set of fronts?

 

Otherwise, this has been a terrific vehicle, we will repair the brakes, and put many more miles on it. Just wanted to rant a little.

One of the reason was caused by the material of the brake pad. I read it on the Freestyle forum. By replacing with a different material brake pad, it'll last longer.

 

I am not an expert, and I forgot which material is better. Ask your mechanic !

Ralph Greene - have you noticed a relatively high amount of brake dust accumulation on the rear wheels of your Montego? Apparently, rapid wear of the rear brake pads is a common problem with Ford's D3 vehicles as recent as 2010 MY, maybe even 2011. The brake caliper bracket design seems to be unusually sensitive to corrosion, which can cause the pads to seize in the bridge connecting the caliper anchor. This in turn results in the pads contacting the rotors and wearing down (generating a lot of brake dust in the process).

 

The part number for revised rear brake pads that LoveTaurus noted is 7F9Z-2200-A for the Five Hundred/Montego. Check with your dealership service advisor as this may have been superseded with a newer part. Also, ensure that the caliper anchor has anti-seize compound or grease applied in the area under the spring clips that hold the pads in place.

 

Best wishes!
