Do you need to replace your brake hoses?

[Comfy Old Boots]

It started out as a routine mini service. I'll clean the calibers and put a bit of copper slip on the rear of the pads to eliminate the squeak I thought. Be good to get rid of the bit of drag on the right caliber I thought.

Anyway, I ended up with this:

LOL!

Interesting...
I'm today actually assembling complete brake system on 1100rt after bike rebuild and front brakes very spongy , I'm using original 97' lines just to test system, eventually will upgrade to steel ones.
Will old hoses cause spongy feeling?

Not sure Mr Pimp but I'm just posting this as a warning for others. Over time the pressure eases off but once the brakes are engaged there is no moving anywhere. It reminds me of a pumpkin for some reason!

Yep, they could easily make them spongy. But really, don't wait to get new lines. Just do it. Apart from being hell of a lot safer, you'll get nice responsive brakes in the bargain

Ah yeah, just want be sure abs works if not I just bypass with racing setup so don't want waist money.

I like the sound of that.

Mine don't look like that, but after reading the posts on here I'm doing mine.
It's an excuse to break out the scanners and swear a lot. and to wear latex gloves...

I might stick some new pads in them while there's no fluid in the system. It would get around the problem of getting the Pistons back in the calipers.

If yours looked like mine you would not move the bike. Locked solid.

In 2010 my 2001 Fiat failed it's not on a brake hose (rubber surface crazed). Replacing all three (OEM parts) made a big difference to brake pedal feel. But at 9 years old I should not have been surprised.

IME binding bike brake calipers have to be rebuilt. Done soon enough the seals might be saved but any alloy corrosion in the seal grooves will ruin the seals. If they are stuck solid they can be it all but impossible to shift.

BMW sell new seal kits for the back brake. Under £20 it's common sense to strip the caliper internally & replace the seals.

Front brakes however only offer new piston & seals kits at £60 per caliper. A full strip at first signs of trouble might save the seals & avoid a big parts bill.

Howdy bendy toy.

My calibers seem vey happy indeed. It's just the hoses in my case. The inner surface becomes up laminated and creates an inner valve that shuts off the fluid creating a lock off.

Wich would the best place to purchase new ss hose set? Just the cheapest from ebay? Fifteen years ago I used to make my own hoses from racing car parts wouldn't bother anymore..

Motorworks. You'll get some support/feedback. You'll need to give them your chassis number to be sure of the right kit. Prices are fine too (they're offering goodridge)

I've used build your own brake hoses but Goodrich are no more costly and can have a swivel at one end to make fitting easier.

Ordering a set of these on Wednesday, I hope that all you tossers don't eliminate MW's stock before I get there!!! Lot of brake hose replacement threads all of a sudden!

That's because they've all seen your original post

That'll teach me not to be helpful until after I've bought the solution

Phew. Sorted!

Many German riders rely on Stahlflex brake hoses. They have an inner structure out of steel fibers instead of textile fibers. So they last longer (and often are cheaper than the original factory hoses. As they are not elastic, they improve the crispyness of the brake.
