I have 4-wheel disc brakes on a 2004 Honda Accord Coupe with 20,000 miles on it. Three weeks ago my mechanic said that I needed my rear brakes replaced and that I only had three weeks left before they're worn down. I didn't believe him at first because I thought front brakes normally wore out faster than rear ones, and I haven't replaced my front ones yet. But then I finally did a quick visual inspection, and yes, the rear ones are obviously more worn than the front ones. Why??

if you have 4-wheel disc brakes, i assume that your vehicle's brake system is hydraulic. if that is the case, your pads should all wore out at the same time. if your rear pads wear out first, it's either the calipers or your hand brake is engaged.

ordinarily , front brake pads wear out a lot faster than rears. (i tend to see a 4 to 1 ratio) front brakes do about 70% of the work to stop your car with the rears picking up the rest. keep in mind that for this reason, rear brake pads are typically thinner than front brake pads because they dont have to do much work. however i do recall seeing some brake pads that were going out pretty quickly on the rears (most notably volkswagen beetle brakes) volkswagen had switched to a softer compound for the rear brake pads due to noise issues. however in a honda , I dont believe this to be the case.
If indeed your rear brake pads are wearing a lot faster than your fronts, I would check the brake calipers. make sure your parking brake isnt engaged, then take a look at the calipers, specifically the guide pins, if theyre dry, lube them a little bit. however if the calipers themselves are seized up , they will have to be replaced ( I dont think ive ever seen one rebuilt nowadays )

Back Brake Pads

i came across this on a 2014 LANDCRUISER, the rear brake pads wear out far faster than front, i suspected the proportioning valve, but for this to be confirmed,
I inter-changed the brake lines from the brake pot (i.e the delivery port from the abs) moved the lines from back to front. low and behold, the wear ratio changed (front started wearing out) but front brake pad are thicker and bigger, they could hold the pressure for more reasonable period of time.

I agree with VULCAN, the proportioning valve may be bad. It restricts the flow of fluid (slightly) to the rear brakes. This allows rear brake pressure to build slower than the front for better brake performance and better control during hard braking.

It could be your calibers are sticking on the rear. You are correct the front should be the first to wear down.
Do you do a lot of city driving 20,000 seems premature to me.
Use the force Luke, I mean trust your mechanic, unless he gives you reason otherwise.

They could be dragging. It happens when they don't fully release due to a problem with the calipers or maybe the emergency brake is adjusted wrong.

front wheel drive vehicles tend to go faster....go to a place that will service your brakes and rotors and give you a lifetime warranty on your brake pads. (they do it) You might have to spend a little bit more but in the end..it is worth it

The proportioning valve could be bad
or it may be an adjustable one and out of sync alittle
Here is a link for the proportioning valve(Combination Valve)
