rear caliper on fire

[Nogwuy]

think its time to overhaul my rear caliper and replace disc & pads. touched the rear brake coming down a slip road off a47, felt like it was binding & brake padal a total sponge so pulled over. smoke and flames (rubber bleed nipple and plastic brake light switch cable both touching caliper alight!) good job i had a bottle of water in my bag.
got home ok after cooling off (front brake only), just stripped rear caliper and pads are almost just metal left, my bad for not checking i know, but no advisory on mot less than 1000 miles ago.

any advise on work needed to the caliper, or on what disc & pads to replace them with much appreciated.

Clean the paint off the pad edges so they slide into place easily.
If you have to tap them into place they are too tight and will stick on when brake has been used.
Copper slip the edges and the back of the pads on the steel has this will stop sqealing of the brakes

Obvious but check the pistons and bores for corrosion and pitting,even the smallest manky bit can stop the piston receeding
Be very careful if you are handling any burnt seals,they can produce a very nasty acid thats not kind to flesh

I saw this disk when listed and did keep it in my watch list.
I take it you bought it? I know it was'nt around for long

[Nogwuy]

Yep I bought one. All the others for simular price were used standard ones so seemed daft not too. He has sold a few so I bet he will have/ get more if you ask?

[Aladinsaneuk]

if it were me, i would replace the lot - new disk but secondhand / serviced caliper

[bigearsbilly]

hoho!

That happened to me on a Caponord a few years ago.

Quite entertaining isn't it?

He's relisted them for a once only special price of £39. Or £37 if you buy it now??

Almost sure to be caused by a mal adjusted rear brake lever...

[moggyvan]

....What Thumper said. If the rod and lever aren't adjusted correctly the brake fluid does not always return from the calliper to the master cylinder.
The same thing happened to me last sunday and I had to pull over and allow more slack in to the lever. Brake disc was a dull cherry red.........
