DIY: ** Rear 20mm stud replacement spacers
 

OK!!! I know everyone wants to get the scoop on this so let's get started.

First of all, this is a VERY easy mod, no troubles what-so-ever!

I won't cover the basics like wheel or brake caliper removal as they're already covered in other DIY articles.

Let's focus on the stud replacement!

1) Get a good set of wheel spacers and studs like these H&R 20mm's from Josh at Stillen

2) Remove the wheel and brake caliper and then remove the adjustment cover on your rotor. ** If your wheel rotates freely with the hand brake off, you do not need to adjust this star adjuster** If it does not move freely, back off the star adjuster a couple of clicks with a screwdriver to loosen the park brake. Count the clicks so you can reset it on re-assembly!

3) Remove the rotor and your rear brake assembly should look like this.

4) Remove the tensioning spring holding the brake shoes together.

5) Remove the star wheel assembly carefully, it is two pieces and will fall apart.

6) Screw on the M12 x 1.25 open ended lug nut and tap out the old studs.

Slide new studs through from the rear and on a slight angle into the hub.

7) Tighten down the studs as you replace them. Use a bunch of washers and and open ended lug nut to pull them into seated position on the hub. M12 x 1.25 nut is required. Use an electric impact drill to seat them easily.

This picture is from the front assembly, but you get the idea!

8) Reinstall the star wheel and spring tensioner.

9) Replace the rotor and readjust the star wheel for proper tension. Add a layer of 'never-seize' to the back of the spacer and mount it on the rotor. Use two open ended nuts with washers to tighten the rotor into place. Replace the brake caliper.

:tup: Excellent write-up, rep point submitted!

Thanks exactly what I needed for my spacer job. +1 Rep points

Nice write up. +rep

Glad to help! I sweated over this mod for months before I got the parts in to actually do it. In the end it was no big deal! Feel free to down a pint of Fosters for me!!

Thanks for the rep points everyone! :tiphat:

-rep for Fosters. Real Oz men don't drink that swill. ;)

:icon17: I used to love the stuff! But then again, it was the Canadian version brewed by Molsons.....

Great info :) I might end up doing this myself and now I know what I need to do :)

Great DIY! +1 Rep

Those are the proper spacers. :)


Thanks for the write-up!

Excellent write-up! +1 rep

Did you use an impact drill for this mod and if so which one do you have? Also, I'll go search for this in a minute but if you also did a write-up for the front spacers could you link to it from the first post or put a link in here somewhere for everyone?

Oh, and nice hammer - did Thor stop by to help with the install. :)

:icon17: I used a Cdn Tire "Maximum" cordless impact driver. 1/2" drive with a 21mm impact socket. The driver is 14.4v NiCD and did a great job as it is a maximum 102ft/lbs force. Went really quick.

As for the front spacers, it has been covered many times. Here is one link.

The one difference I had was that you don't need to mod the shield to fit the bolts thru...

Go to my Mod Album to see all the pics for the front install.

As for the hammer... it is a 3lb sledge that is EXTREMELY handy to have around in tight spaces with limited throw. It packs a nice punch with one small swing! Thor would approve....:bowrofl:

Yup!
