Spooky huh?

Now it's funny you should ask that Greg as I was just about to post a new thread.

I serviced the 1150 today (16,000 miles overall and 4,000 since last service). New tyres and rear wheel removal meant I could finally get to the rear caliper to check the wear. Now I reckon I rarely use the rear brake and as the front pads were well within their limits I was gobsmacked to find the rear down to the metal.

I read somewhere that the pin gets corroded and the rear pads can be gone within a few thousand miles.

Luckily I had ordered a complete set from Motorworks so I could replace them but has anybody else noticed significant wear at the rear ( oo er missus) ?

BTW the Tourances were at 3mm front and rear after 10,000 miles. Not bad I reckon. I've treated the new ones with Ultraseal this time so it will be interesting to see the wear this time around.

Cheers

As per front pad wear post.
I changed the rears at about 20,000 mark on my 1st 2 GS's

No problems, but like Dick, I have the rear wheel off for a new tyre. Knowing of several folk who have worn their rear pads in 6-8k miles, I decided to have a good look at the original pads on my 16k miles bike. They will do another 5k easily by it set my mind wandering.

You're doing better than me then Greg.

I copperslipped the backing of the new pads and the pin so hopefully that will ease the wear next time around.

When I bought my GS it had 10k on the clock and was already on its 2nd set of rear pads whilst the front were like new. It has now got 17K on the clock and the front ones have loads of life left and the rears are looking like they will need replacing soon. I would suggest from this that the rears do wear down significantly faster than the front which suprised me.

just my tuppence worth.

Have Fun

My mileage is mainly open road very little town work, his may explain why I get about 12000 to a set, are the folk with low milages mainly commuting?

Just did Edindburgh MAG's demo all slow town riding finished of my rear brake pad in about 10 miles I thought I had a 1000 + to go.

Back brake?........Ah, do you mean the "showing off brake"?
 
On my first (non ABS) GS I needed new rear pads at the 6,000 mile service. Sawbridgeworth dealers really pissed me off by insisting that I must have been accidentally dragging the back brake on. In fact I hardly used it.

Once I knew about the problem (not from Sawbridgeworth, who claimed there was no problem) I kept the retaining pin copper greased and had no more trouble. Sold the bike with 24,000 miles and the original front pads.

My new GS has the EVO ABS set up which links front and back brakes. I'll have to wait and see if this makes a difference.
 
I have a GS with EVO Brakes but they ain't linked !!:confused:

Are there two types of EVO Brake systems on the GS ??????????

I kinda figure that cause the RT has Linked Brakes, some folk think the GS has the same.:(

Tell me if I'm wrong...............

According to my Riders Handbook my new GS has partly Integral Servo Abs. Front brake operates both front and rear, whilst rear operates only the rear.

Heavy town driving just seems to eat the rear brake pads - just done 6ooo miles in a year and had them replaced.....

How do you get that much mileage out of rear pads.

You obviously don't use your brakes. . . . . . . At all! (as the front is linked)

Bet you can get 30,000 miles from a rear tyre too.
:angel :clap :eyebrow
 
just over 4K from mine, but thats down to a lot of london traffic. fronts doing ok at the moment ;)
 
9000 is average

This is due to the rear brake being non floating pistons or something like that and is normal, new BMW pads have the inner pad made 1mm thicker than the outer to allow for this eneven wear, you'll replace 3 sets of rear to 1 set of front.

The piston corroded on my rear caliper.

It was working fine with the old pads. However, the corroded piston prevented the caliper being opened wide enough ot fit new pads.

Jim at Rydales contacted BMW. They supplied a new caliper for 50% retail even though my bike was over 3 years old. (It only had a 1 year factory warranty)
 
Got 5000 miles out of the rear with the inner pad at the metal and the outer not too far behind. Replaced with EBC pads (need a bit of filing) and greased the pin. Have put 11000 miles on them and they're down about half way.
