1984 FJ11 Brake Rotors

[wainot-Phil]

Hi Alan , I found and measured the 2 x  S/H  FJ1100 Rotors that I have ,Looks like they are worn out ,They only measure about 6 to 6.1 mm ,, better off with the Rotors you have ,,cheers Phil

      Once you have 320mm rotors, blue spots, EBC HH pads and a 14mm R1 master cylinder, the OEM brakes feel like absolute shit. Try mine in December and see what I mean. 

This

how you doing Pete ?

G'day Jools, thought you'd dropped of the edge of the planet, been a long time.
It would be great to have you down here in December for our Manshed Day, still a bed or two up for grabs. My FJ has had a bit of work done to it since we last spoke. Won't go into it now but happy to fill you in when we see you in December. Hope you can make it.
   Regards, Pete.

I had !!

I'm not going to commit to anything till that bike is up and running sweet, but fingers crossed we can talk shit over a few coldies eh ?

[oldktmdude]

   Jools, just get it going good enough to get it down here in December. We'll make it sweet over the weekend. Even if you don't have it on the road by then, drive down in your car and either ride one of my bikes or I'm sure there are others willing to lend a spare bike.
   Alan, my apologies for hi-jacking your thread. 
Regards, Pete.

Hi Alan

sorry to hijack your thread...............

Pete, refer to my other thread

No Worries Guys,

We are all in the same family. 

There is only so much that can be said about brake rotors

Cheers Alan

As long as you still have enough thickness to work with, one can resurface the disc surface with an angle grinder and an abrasive pad. Then new pads to break-in and you are down the road

Angle grinder? Shouldn't it be done on a lathe?

[Pat Conlon]

To remove old brake pad transfer layers, I've had good results using my cordless drill and a Flex Hone brush



Spin the wheel one way, scrub, then spin the wheel the other way, scrub....leaves you with a nice cross hatched surface.
This is used for only cleaning the rotors. Not a replacement for turning your rotors on a lathe.
When changing brake pad compounds (e.g. going from organic to sintered pads or vice versa) you must remove the old material built up on the rotor (called the transfer layer) before bedding in the new pads.

"DO NOT TRY THIS AT HOME" or anywhere.

If you want to resurface your rotors this way, fine. To suggest on a public forum where someone might actually try it is not only a bad idea, it's dangerous. Removing pad material is another thing.

If you think there aren't people out there who consider a cutting/grinding wheel to be an abrasive pad, you'd be wrong. I've seen it.

Pat's on the money, cordless drill speed and a non aggressive tool that's not too senstive to angle or pressure. Not too harsh or hard. IMO an angle grinder is too fast and more likely to burnish than abrade.

There are people out there whose ignorance of all things mechanical beggars belief and there's nothing wrong with that if it's not your thing, until, they fancy the notion of having a go at a few jobs themselves, and that one sounds easy.

I wouldn't even bother commenting on this but we are talking about brakes and ripping into them with a hand held aggressive tool, possibly by a complete novice, on rotors that are only a few mm thick to start with.

IMO

Couldn't the same reasoning also apply to those that showcase their bling, such as an automatic chain oiler, stainless steel braided brake lines, or a GPS unit? It's not a stretch to envison a mechanical novice installing items like these and having disastrous results. Either with their install or use.

Where is the line drawn for those that post for the benefit of others, but shouldn't because of it being deemed a dangerous practice by others?

[Pat Conlon]

Marty, do you have an angle grinder?
If you do, then you know what Noel's talking about. Those puppies spin at 7,000 rpm, along with an abrasive pad would be a bit aggressive I'd say.

Get the right tool for the right job.

Brakes are important.

[FJ1100mjk]

Get the right tool for the right job.

Exactly

Get the right tool for the right job.

Yep, See reply #5. You're welcome.

Marty, do you have an angle grinder?

No, but I've spent some time using them over the years.

[Pat Conlon]

Exactly

So Marty, you, personally, would use this on your brake rotors?
