Bedding in brake pads?

[Itchy]

How long/miles does it take to bed in brake pads? , mine are looking a bit low but I don't want to change them like a day before the MOT test (last time I changed them 3 days before but managed 270 miles before taking it into MOT which it passed) .

Any suggestions?

Bike:
Single front disc , single rear disc , NTV,

Also
ZX6R 2001 model

I usually try and take it easy for about 50-100 miles, although on the R6 I bedded the pads & disks in on the race track within about 5 laps of Snetterton.

You've bought a ZX6R or wanting to know for when you get one?

I use sand paper and sand the disc from the middle out and in.
If the disc is worn sand the edge of the inside and outside of the pads.

Just fit them and take it easy on the brakes for the first couple of hundred miles. You want them to bed them in gently and not get them too hot straightaway or they will end up glazing over. Even with new pads in and a half decent disc it should sail straight through the MOT with very little bedding in.

Surely none at all?

If the testing center replaced them they wouldn't bed them in before they passed it would they?

Hmm righteo then , I'll change em a week before and my 300 odd mile weekly commutes should bed them in nicely!

Thanks

The MOT braking tests are not difficult to pass. Infact it's very rare to here of anyone failing for poor braking performance. Binding brakes yes. Leaking hoses yes. Cracked discs yes. Poor performance no.

The front brake on my cb550 is lethal, really attrociously bad. If you've only ever ridden modern style bikes you wouldn't really understand. It is not a lightweight bike either. Still passed its MOT well within the margin for brake performance.

Not necessarilly totally applicable, but this is the correc t bedding in procedure for race pads (off performance friction's site).

Bedding in procedure

Correct bedding in procedure can increase pad and disc life.

First, ensure the disc is clean and free from any other pad manufacturer's material before using our pads, other manufacturer's pads can leave an uneven transfer layer on the disc and cause bedding in problems.

The rider should build temperature in the disc and pad gradually over approximately 4 laps. Once our pads are fitted and the rider is ready, conduct an out lap at about 50% normal speed and apply brake pressure in the normal way (do not keep hold of the lever in an attempt to induce heat in the pads, this will thermally shock the pads and cause them to glaze).

Then conduct a further 2 laps progressively increasing the speed and lever pressure. The fourth lap should be at full speed and normal brake pressure.

The bike should then be brought into the pit, making sure to conduct at least two heavy brake applications with even brake pressure, this helps to create an even transfer layer of material on the disc. Then let the brakes cool for at least 5 minutes, this ensures the pads and discs have heat cycled in a controlled manner that helps prolong disc and pad life.

The brake pads are then ready to use at full race pace, remembering to generate heat into the pads on the out lap.
