How long should w126 front brake pads last?
I put new pads on the 1982 300sd about 9 months ago. They were not Mercedes textar pads. I bought them before I knew textars were best. They came from a euro parts dealer. They were his best pad. They have given no problems or noise when stopping. I also replaced the wear indicators.
Yesterday, my brake light started flickering. I know that means the wear indicators are letting me know its time for pads again. How long should I typically get out of a set of pads? Do you get more than 10 months out of textar pads? Would like to know. I do a combination of city and highway driving 50/50.

This question is very hard to answer, however I will give an example to try to explane it.
My Father had a 83 Buick Riveria. (I know, I know Bad words) I had a 82 Buick Riveria My Father would get 60K to 80K from a set of dealer pads. I would get 20k to 25 k from the same pads. Later I got my fathers car when it had 170K miles, replaced the pads for the second time and then got 18K out of that set. Moral to the story, It depends on the driver, not the car. By the way, it looks like I will get about 20K out of my 126.

I wouldn't rely on the sensors 100%.... Many times I've seen sensors go bad or the sensor wire break causing the light to flicker. Might be worth pulling your wheels this weekend to be sure

Got 20,000 miles out of mine
I have the same year Benz and model that you have. I purchased Mercedes pads (not sure what textar pads are) for the front of my car. I got 20K miles out of them in about a year and a half time period.
I do 80/20 highway/city driving with my car. I believe the composition of the pads are designed such that they dissipate faster, and don't compromise the rotor. I am probalby abnormally rough on my brakes though. I thought I should have gotten more life out of them as well.

It really is hard to tell. It also depends on the condition of your rotors. I believe my front rotors were originals, badly worn and uneven. Sticking calipers can cause 1 side to wear much more than the other.

I'm afraid the number of months they have been on there is meaningless, did you cover 10 miles or 100,000 miles in those months? Pad life is, as has been stated, a function of the type of driving you do, the distance covered, and the condition of the calipers and rotors. Sticking calipers could cause premature wear on a set of pads. Kevin

It depends on how many "Delta-Vee" events have occurred.
For Rocket Scientists, Delta-Vee (I'll use DV from here on) is a shorthand way to express a change in velocity. For instance slowing from 60 mph to 50 mph is a DV of 10 mph, while 60 mph to 0 mph is a DV of 60 mph. To slow the car requires dissipation of energy, via friction that transforms the kinetic energy of the moving car into heat, while to speed up requires adding to the kinetic energy, by burning more fuel to add to the kinetic energy. The friction of the brake pads on the rotors mechanically abrades some of the material, causing pad and rotor thickness decrease. Therefore, the pads and rotors are capable of providing a finite number of DV events. Every time you use the brakes you are subtracting some 'life.' How much depends on how much DV. How long in time, and how far in miles you go between these events is quite a variable. I can cover 120+ miles across the state and not have a DV event, then go 1.2 miles in rush-hour traffic had have 10 DV events. That's how a Rocket Scientist would say "Your mileage will vary!" Best Regards, Jim |

I have about 10k on my Textars now and they have at least another 10k-15k of life in them.
I do a lot of stop and go city driving and in traffic. Just go easy on your brakes. Light stops and don't speed up to a red light.

depends on how you drive,
I average 15-18K on my 300SD

I wore the front pads out in my '84SD every 10-12k miles, consistently. Always used dealer pads.

Not to make any of you feel bad, but, IIRC, PEH can get something like 80K on a set of pads. I believe that he has never replaced one of the sets on one of the W126's.
I'm quite sure that I can get 50K on front pads. Just let the engine slow the vehicle down. You aren't going anywhere when you pull up to the line at the red light. |

My SDL had new pads 30,000 miles ago, and they have yet to reach 50% worn. Most of my driving has been 150 miles trips one-way, no stops, no brake use to slow down.
As I said above, your mileage will vary. Best Regards, Jim |

Dealer (OE) pads are very soft and don't last as long, under the same driving habits, as other pads such as PBR Deluxe, Pagid or some of the ceramic pads now being made (and not easy to find for the 126 chassis).
One thing that really helps extend life of brake pads is using lower gear while driving in slow moving or stop and go traffic, engine braking is an excellent thing in diesels and you would be surprised at how much that helps slow a car and reduces increase brake life. I once selected "S" for this purpose while driving someone's car and they said "why do you do that, you'll wear out the transmission, won't you?" to which I answered no, just good driving habits!

I only get about 12,000 miles on my 300sd's pads but I live to dry fast and brake hard. Plus I have dust shields, which are said to expedite the process. I don't care though, because I change my own pads and they only cost me like $34 (oe pagid of course!)
