Record miles on brakes? - Page 2 - PeachParts Mercedes-Benz Forum

This came up a few months back in the diesel section.

My rotors lasted 300,000 miles and the feedback I got is that they could have kept going

The OP talks about front pads, so my post doesn't count, but I'm pleased with what I have to report.

Wifes rear pads on a 2006 Toyota Avalon were changed at 183,000 and 1/3 of the pad was left. Could easily have gone past 200K.

Cool!

Flushing brake fluid once every year or two will not only extend the hydraulic life of your brakes, but because it keeps caliper pistons operating smoothly it will allow the pistons to push back quicker decreasing pad drag, thus having a fractional improvement on friction component life.

One of the things I learned from MB way back in the seventies was to maintain clean brake fluid. Doing so will almost eliminate brake and clutch hydraulic problems because of internal corrosion prevention.

My late Father, God love him, thought that changing brake fluid was silly and wasteful, but I have seen the results of it and highly recommend it.

I did that at least once.

This is excellent advice.

I get about 60k out of the fronts on my truck, 1/2 ton brakes are undersized. 3/4 tons and up are 100k minimum. Actually for any modern truck 100k is minimum mileage for any service beyond oil changes.

My truck which I found out when I did brakes has SS brakes on it, with 13in and some change front rotors. Why? The PO was a utility company and I guess they spec'd very big brakes for their 1/2 tons. As a result I get 60k instead of 30k...

t walgamuth · #25 07-23-2014, 09:46 PM

That is big for a half tonner.

My brakes are even small compared to the 14's. 14's went to rear discs again and the fronts got larger.

It may be somewhat different frequency by regional temperatures and weather etc. If the fluid in the master cylinder is not nice and clean it is contaminated by something. Rubber seals deteriorating for example.

The brake fluid should be periodically flushed and replaced. In the overall picture it is much cheaper than not doing it. The stuff will always find a way to absorb moisture . Even if it has to get by seals.

Some vehicles obviously more than others. Even condensation may play a role. In my area every three years even is far better than never. Even a simple gravity bleed is much better than nothing.

No getting the air out in most cases by a gravity bleed as well. You cannot ever get all the old fluid totally out with a twin piston caliper. Unless you take everything apart anyways.

One of my 300 SDL cars had about 190,000 on all four pads when I sold it. They were still very good. 85-90%. I do a lit of highway driving here in WY, MT, NE and a little in overpopulated CO.

At the other extreme, a young English fellow named Lewis lunched a brake rotor with well under 100 miles on it while driving a high performance Mercedes:

Impressive.
