Build This years homework

[REZARF]

Had some time today between World Cup games and YouTube… we had an all day rainy day, which is rare here in Montana. We had snow today a few 100 feet higher up than the valley I live in.

Anyhow, I attacked the brake wheel cylinders.

Here is where we left off. Disassembly and “cleaning.”

Got them all bagged up. Every nut and bolt. Only missing 1-2 parts but they’ll turn up I’m sure.

We masked them off front and rear and u hit them with some rust converter and Rustoleum industrial enamel. The enamel is sure to lift off as soon as we spill some fresh DOT Brake fluid on them. Haha

This one happens to be number our number 2 cylinder. I did number one without the camera so I could focus. Here’s how it went.

First off a quick cleanup of the bore. I used 320/600 sand paper. The pistons were way more corroded than the cylinder was. I bet I could have reused most of my parts but the new rebuild kits from @cruiseroutfit fit the bill so while we’re in there, we’re replacing parts!

Hers the kit number from Kurt and the gang… thanks again Bryce!

Quick brush with a wire brush and some CLP, I used some 320/600 grit to clean up all contact surfaces.

A dot of anti-seize on the adjuster bolt and on each of of the pistons. This is where nearly all the frozen cylinders were corroded. Side note, I hate anti-seize as it’s such a mess. However after owning my FJ40 for 27 years I have come to live its benefits. A little goes a LONG way.

Fresh rubber seals go on easy. I started adding a little lube to the rubber so it would seat easier. Worked great.

This is the harder of the two boots to get into place. I found putting it on after installing the piston to be the best way to do it.

Here is the guts of a cylinder. A spring, a plunger, a seal, the piston and lastly the boot.

Spring and plunger go in first.

Seal goes in with the “cup” facing inwards.

A dot of Anti seize…

Smeared, and spread thin…

Rubber boots fitted…

A dot of blue lock tight on the adjuster arm bolt, split washer and screw and you’re done.

I went ahead and cleaned up the threads on the bleeder screw and add a dot of antseize.

Rinse repeat… well almost. I busted the plunger on wheel cylinder #3, gotta find a spare or JB weld mine back together.

All lined up for their beauty shot.

The Toyota ones have their sweet TEQ logos, L or R and a series of numbers 15/16, 1/4… etc.

My one corner (rear passenger) had two aftermarket wheel cylinders. The kits I had in hand didn’t fit these but they were in good shape so I cleaned them up and lubed them up and reinstalled the guts. I might pull off two OEM ones of our parts cruiser, but I’m not THAT motivated right now.

Here is my busted part.. anyone got one laying around? I need the cap thingy at the bottom of the spring.
