I'm not sure exactly what you mean.

What is the problem ?

Were the rear brake pads replaced at the last service ?

If they are the original Brake Pads - how many Kms in total on your Trophy ?

If you need new Brake Pads, they are Triumph Part Number T2025045.

hi
sorry for the delay...maintenance at 32734km done by the first owner then rear pads at 43000km ( was ok 10000km)
After 49000km maintenance; my rear brake pads were dead at 50500km then again at 52620km then again at 54800km.
I checked piston's ability to move-)ok.put some grease on 2 axes that guide the block.
Then now at near 60000km again pads dead (Nissin original pads).
Would it be that they change somethink during maintenance regarding rear brake ???

Advise me if you have any idear.

Regards

To be sure I have it right you have worn out the Rear Brake pads after
2,120 Km ( 1317 miles ) { Replaced at 50,500 and worn out at 52,620 }, and
2,180 Km ( 1354 miles ) { Replaced at 52,620 and worn out at 54,800 }, and then
5,200 Km ( 3230 miles ) { replaced at 54,800 and worn out at almost 60,000 }

For comparison my Trophy has done nearly 11,000 miles ( 17, Km )
and is still on the original Rear Brake Pads, with a few hundred miles of wear still left on them,
so the wear rate on your Rear Brake pads is WAY too high !

When braking are you using the Rear Brake mainly or the Front Brakes ?
( The majority of braking should be carried out with the Front Brakes ).

Are you accidentally dragging the rear brake by resting your foot on the brake pedal ?

Either of these could cause excessive Brake Pad wear on the rear pads.

As you have checked that the Caliper is moving freely on it's Sliding Pins,
then the wear can only be caused by the brake pads being applied to the Disc,
and this may be due to the Caliper Piston sticking.

Go for a ride, and stop after using the brakes several times
then put the Trophy onto the Centre stand with the Gearbox in Neutral,
and make sure the rear wheel can be turned easily by hand.

If it doesn't turn easily then the rear Brake pads are binding,
indicating that the Piston may be sticking.

IF this is the problem, it may be possible to overhaul the Caliper,
with a new Piston and Seal set ( T2020050 ), or the complete Caliper may
need to be replaced. ( T2023053 or T2025040 - the Parts Lisiting is unclear ).

If you have got 50,000km from the original set of pads, then had only 10,000km out of the next 3 sets, there has to be a problem. It is either rider error (dragging the brakes) or a mechanical fault, such as a sticking piston or calliper. Seeing as the brakes are linked, how are the pads in the front coping? I have 85000 miles (130,000km) on my bike and brake pad wear has never been a concern to me. Yes, they wear out, but not as quickly as you are experiencing.

Thanks for your answer
rear wheel is free after using rear brake for a while...
Seems that last sets of pads not made with the same matérial as the one i had when i bought the bike
Do you have the part number for the original set of rear pad

There’s a complete Parts List here :

Spare Parts List.

I’m away from my PC at the moment and using my iPhone,
so not easy for me to look up the Part Number for you !

I have a set of Rear Pads that I bought a year and a half ago
so I will double check later to see if the Part number has changed,
which I doubt very much, even if the friction material used has changed,
which I also think is quite unlikely.

The Pad Set I have is marked ( on the Box ) : T2025045.

The latest Parts List has the same number.

As shown, the genuine new Pad material has a Golden colour,
with a silver coloured backing shim on each Pad.
