3500 miles on my Trophy and got a advisory on brake pads on the rear which seems rather ludicrous.

It's got linked brakes but don't see how that would affect it. Front are fine. Tester said the rear wasn't dragging at all.

Anyone had that sort of wear on their brake pads or got any ideas?

I don't ride with my foot on the brake pedal either.

^^^What ?^^^

Yes, the tester showed me, I had to get up from my chair, put down my mug of tea and amble over to the bike to have a look. I don't need to look again.

I'm curious if anyone has any ideas or come across pads that have worn so quickly?

Otherwise I'll just stick some new pads in, no big deal.

Then I'll tell everyone how the workshop smelt of minge, even though the only female in there was on a 20 year old Pirelli calender. You'd like that.

Hi

Linked brake system I presume is activating the rear a bit when you use the front. If so it might well increase wear.

All the best

This is how Triumph described the linked system. My problem is that there is basically sod all wear on the front disk pads and if it's working as said and it was me resting my foot on the brake pedal surely there would be noticeable wear on one set of front pads.

This motorcycle is equipped with the Triumph Linked Brakes System,
combined with the Anti-Lock Brake System (ABS).

In this system the rear brake is linked to the two lower pistons in the front right hand brake caliper.

Operating the rear brake pedal will partially operate the front brake,
allowing for balanced braking under all riding conditions.

Operating the front brakes via the front brake lever will NOT operate the rear brakes.

The rear brake circuit contains a proportional control valve (located under the left hand control plate)
which limits the pressure to the rear brake once weight transfer to the front wheel begins.

The linked front brake circuit contains a pressure delay valve
which delays the application of the front brake during initial application.


I'm wondering if I just had a bad set of rear pads.

That's a lot of miles if you ask me.

MTB brake pads can wear away in a couple of rides and they are almost the same price.

It also depends how you ride and what sort of riding you do obviously. If you be a racer then pads will wear fast, if you ride a 4 stroke along motorways then they'll last a long time.

Hi

Is a bit odd. 3500 is nothing for bike brakes on most bikes. From that description, possible it could be doing something strange when pulling the front brake. Good luck debugging that!

All the best

I just dug out the brake circuit from the Triumph site Brick Wall

https://www.worldoftriumph.com/triumph_motorcycle_parts_locator.php?block_01=&block_02=100061479-0-2&block_03=621910


New pads it is then !

Be aware that you may have inadvertently been sold counterfeit brake pads.

I had a counterfeit pair on my CBR. They lasted <200 miles.

3500 miles is nothing, i'd expect your pads to least 3-4x that amount.

I'd advise you take the pads out and to see if there's any markings on it to see what make/brand they are.

I've had cheap soft compound pads wear within 5-6k on a non-linked brake system. Is this possibly a problem you have?

I had a Varadero with linked brakes, the rears wore at an alarming rate.

Now I have unlinked brakes on my Versys and the rear pads are only just nearing the end of their life at 37,000 miles. I use both front and brakes so no idea why they have lasted so long.

My shortest rear brake pad life was 80 miles on my DR350, a day of heavy clay and waterlogged green lanes.

The fronts on my Nazi Tractor are on the way out again, at under 2000 miles, again. EBC and now Brembo. Seals were replaced, pistons cleaned, disc doesn't seem to be heating up, but it must be binding, there's no other rational explanation.

On my Bandit 1250 the rear pads never lasted more than about 6,000 miles.

There was nowt wrong with the caliper, it wasn't binding, that's just the way it was - maybe because big, heavy bike?

However, the exact same caliper is fitted to my current steed and the rear pads still look new after 13,000 miles.

Go figure.

My BT1100 were about gone on the rear by 6000 miles, I put it down to riding off road bikes too - so steadying the back end slightly without thinking. Front were not even half worn at same miles.

That's pretty much what I assumed but I'm not aware of riding my current bike any differently... Confused

Single disc on that Roger, or both front brakes?

I had linked brakes on a Goldwing 1800 but can't honestly remember if I even changed the pads on that. There again if you had the same it's possibly just something you have to live with when you have linked brakes.

Single, the 650 800s didn't get dual discs until they were 700s. (BMW Rolling Eyes)

It did well over 6000 on whatever pads were in it when I got it, before it started binding. I overhauled it then, but I guess it needs überhauled.

Linked brakes pah! Get some braided hoses, repipe it so your brain links it, or take the brake pedal off.

OGR.

I agree. Never really been a fan of linked brakes but with a totally integrated system with brakes, ABS and traction control I don't think I'm going to start dismantling it . Laughing

Pads are cheaper.
