Cheers for the responses guys. Here's how I've been getting on with replacing the short studs. I posted this in my "Extended Studs?" thread but it's here to to keep the continuity of the blog.
Today I have mostly been, fitting longer studs to the rear.
Step 1:
Loosen the rear wheel nuts,
Chock the front wheels,
Take off the hand brake,
Jack up the rear on the center of the axle,
Lower back onto axle stands.
Step 2:
Remove the brake drum. There's probably a way to get in from the brake back plate to undo the adjuster to make it easier, but I managed to just wiggle the drum off. It didn't even really need a tap with a hammer to free it up.
Step 3:
Remove all the brake parts so that you have clearence to work. I find its best to lay these sorts of parts out under the car in the order that you remove them to assist with getting them back in. I was working without a haynes and I've not opened a drum brake for a long time so I just made it up as i went along.
Step 4:
Remove the first stud. Only remove and fit one at a time! You need the other studs in place to lever against when pulling the new stud into place.
A Household/DIY claw hammer isn't going to cut it here you want something with some weight.
Step 5:
I thought at first the studs were too long to fit, but then with some giggling and wiggling I found that this part of the pressing gives just enough room for the +20 stud.
Step 6:
Pull the stud into place by sliding a socket over it then tightening a wheel nut up on it to pull it through the hub. A washer between the nut and the socket would help but I didn't have any big enough. Also a good smear of grease between the nut and socket will reduce some of the friction and make it easier do up.
Step 7:
Repeat steps 4 - 6 three more times. Put the brakes back together. If you cant remember hoe it went, get the drum off the other side and use that for reference.
Now here's where I ballsed up. I must have wound the adjuster further out while re-assembeling the brakes. The drum was an arse to get back on and now the brakes are binding. I did the same the other side too, I kindof hoped that they would free off after a drive but I need to take the drums back off and re adjust. I think I might also have to change the brake fluid, i suspect I might have boiled it.
The other issue I have is that the splined section is about 1.5mm longer on the replacement studs. I'm not sure if the drum has seated properly. There doesn't seem to be any vibration, but if there is an issue I will just drill a slight clearence on the inside of the drums.
So rather than getting on with the front, I'm still sorting the rear. Bumhats.
