rear brake rotor replacing

Post by fred1diver »



hey everyone, finally received my brake rotor, now how hard is it to do, or should I let my mechanic do it for me?
things to consider, I don't have a garage.

Just the rotor? Pretty simple as long as you don't need to mess with the master cylinder or caliper.

Remove the rear brake caliper - do not disconnect it.
Remove the wheel/tire.
Remove the rotor from the wheel and install the new rotor.
Reinstall the wheel/tire.
Compress the rear brake caliper so that the brake pads fit over the new rotor.
Reinstall the rear brake caliper.
Apply rear brakes until brakes return to normal.

I've been told the hard part is taking the rear wheel off, any tips and tricks to share?
there isn't much info on youtube either, only one video shot in the dark :(

Getting it off... and back on too is a " ballet " with a lot of small steps .
I use a small table lift , safety ties so it will not fall over, several bungee cords to tie stuff up , a long lever 2x4 and a 6x6 block as a lever base , and a scissors jack to fine tune where you want the swing arm .

You also need some Moly 7 grease , and a torque wrench with a 26 mm socket , or its inch equivalent . Its also a great time to re and re the rear brake pads. I save a all sorts of electrical time by just loosening the left saddlebag , and gently tying it up , out of the way .( not disconnecting the lights )

More or less , its like this :

Bike on a smal table lift , as high as I can get it .
Left saddlebag gently up and out of way, Right lower shock bolt, and tie shock up, Axel nut , left shock lower bolt , and tie shock up , jack or lever up swing arm , untill axel clears top of mufflers , remove axel ( watch for 2 spacers ), remove caliber unit,and tie up , pull ( wrestle ) wheel off splines, lower wheel, and remove .
If bike is way up in the air on a table jack , this step is a lot easier .
Might have to deflate tire here, too.

Grease splines, replace brake pads, replace and torque down rotor .
Clean and grease caliber slider bolt. Check brake pistons .

now :
lift wheel into position , Wrestle it onto splines , ( Lots of swearing here ) , seat wheel on greased splines, re do caliber, spacers , axel bolt , and big nut, finger tight, align with caliber mounting plate hole , and insert left shock lower bolt ... the easy, tapered one .

The right lower shock bolt is not tapered, but square headed and is really hard to insert . I eventually filed a small shoulder on this bolt, and use the scissors jack on the swing arm to PRECISELY align the right lower shock bolt hole . Its a real pain .

The rest ( torquing all bolts, axel nut ,pinch bolt, caliber, saddlebag , re- inflate tire etc) is pretty easy .

Have fun

When taking rear wheel off my 1100 I'd get the bike on center stand, then straddling the bike would tip it to one side enough that a helper could put a piece of 2x6 under the Centerstand pad. then tip to the other side (on the 2x6) to put 2 pieces 2x6 under the other pad. Back and forth until both center stand pads are on top of three pieces 2x6. That is high enough to remove the rear wheel on an 1100. Might work out ok on a 1200.

I didn't want to try that on my 1500, I bought a Harbor Freight motorcycle lift for that.....

Several other tricks, it just depends on what you have available. You need to get the rear of the bike high enough that you can roll the rear wheel/tire out. So what do you have available... A lift? A come-along? Jack stands? There are even some that use a blanket and lay the bike on the ground...

I can have it off in less than 30 minutes, but that is using a lift and not removing the bags completely.

well it's finally done, passed the safety with flying colours, the bike is now plated, the only part of my day that was a bit frustrating is when my mechanic told me my rotor was still within acceptable specs, the guy at the safety check place was being too picky, so 360$ for no real reason, well at least I know the bike will stop properly
the god part of the day was giving my 11yo son his first bike ride :D
he's hooked
