    Posted: 12 Jun 2013 at 8:34pm
I am posting for a neighbor who has a sweetly running 1948 WD45 he said (but in looking online for him, maybe WD). He has the manuals, but says they don't tell how to change the brake pads.  Said he had talked to other locals with similar tractors and they have brake pads but don't know how to change the brakes.  So,  I said there were folks online who would know and I would ask for him (he doesn't do computers).  PLease and thank you.  If you can guide me in asking a more specific question, that would be welcome.  Thank you.

You remove the top covers and loosen the adjuster screws. Then remove the 3/4" rods on the bottom that hold the two lower ends of eaah shoe together. This is no simple task unless they've been well soaked for a long time by hydraulic fluid. They must be driven, pulled or drilled out.Unhook the upper part of the shoes from the brake activators and pull each one out the top.

And one more thing! Unhook the brake acuator rods from each peddle and unscrew from the inner activators or you can't get the shoes out..

The hard part will be getting those pins out.  The pin is inserted from the outside bottom of the brake compartment.  There is a small bolt and flat plate keeper that prevents the pin from falling out.  The pin anchors the two halves of the brake shoes together in the bottom of the brake compartment.  With this pin out the shoes will come up out the top access hole.  Again the pin may be frozen in place from rust and dirt and may require much heat and penitrating fluid along with using a big pair of vice grips or even a pipe wrench to try to wiggle the pin.  In extreme conditions some have resorted to cutting that pin from the bottom into pieces and then driving them into the brake compartment and letting it fall out through the hole.

danny r has a very good post on this job, if you end up needing to cut the pins out do it outside as there will be lots of smoke from the burning mouse nests.  Also wear a good set of welding leathers so you don't get burned as you cut the pins.  I do want to encourage you to fix the brakes as they are a BIG safty issue several of us on here have done it so if you have further questions ask.

I just did a set on a friends tractor and I welded a 3/4 in. nut to the ends of the pins then soaked them with PB blaster. You can then put a wrench on them and eventually get them to turn. After loosening them up this way, they just pulled out.  Left the nuts on when we re-assembled them to make it easier next time!!
