Keeping the DIY moving along with, How to overhaul Brake Calipers and replace Your Brakes by yourself.
I promised it, and here it is, today i completely rebuilt the rear brakes on My Subaru, and stopped to take pics to show you good folks.
^^ look at that rust, just look at it..... the calipers were actually rusted solid, from 3 brutal Japanese winters left outside to rot in the snow. it took a 3 pound hammer and some "persuasion" (re:cursing) to get it all off.
The drip tray is for brake fluid. simply 2 14mm bolts on the rear of the Caliper, a 14mm bolt on the brake line, and some hammering. for real. 2 tools to remove the brakes. looks pretty nasty at this point. so i busted out the drill, a wire brush head and a can of paint before using Brake Cleaner on the new discs before sticking them on.
The Suspension components will be replaced, so a bit of overspray is no problem now. today is about the Brakes, and using the chance to paint the inner wheel wells. The Dixcel Brake discs are great value at $90 with 20% off. and no tools needed to put them on. they just slip on. now for the harder bit. -Rebuilding the Calipers.
here is my buddy showing me how to use the air hose in the brake hose bolt hole to pop the Cylinder out. The original Calipers were toast, so we raided his parts bin for some Calipers from a Legacy GTB. (note: for this swap, we used the mount part of the Calipers from the Impreza, as the discs are smaller, the Cylinder part fits when you combine them, these will be a custom mix setup using Subaru parts)
once the seal is broken, tear away the rubber and pull out the Cylinder, like this:
remove it, clean thoroughly, with Brake cleaner, and air hose, or a clean cloth. i took this chance to clean up the parts as i went, and cleaned it twice.
you can order a rebuild kit online, or from a local parts store.
it contains all the rings, seals and rubber dust covers you will need. and is easily available on the internet, or from a local parts shop. the kit i am using is from Akebono, the actual manufacturer of these brakes. - $30
there are only 3 of the larger rings, - a rubber seal, a dust cover ,and a metal circle clip, because one caliper had already been done.
the rubber seal goes in first, then the dust cover, and the metal clip goes in last, the only tool i used for this is a small hook tool, but other things might work for popping the clip in.
painted up the Legacy part in Silver, and the Impreza Part in Metallic Black. (bonus paint i got floating around)
using hi temp Silicone Grease for Brakes, and Wedsport Revspec Brake pads that were on sale at you guessed it, 20%off. - $50.
fitted the side pistons and dust covers using parts from the kit. and put in the pads, how you put the pads in is up to you. remember to use the brake grease between the pads and Caliper surfaces to stop squeaking. and you will have this.
A rebuilt Caliper like new,with some decent pads in it. Time to put this badboy on:
erm, i left the drip tray on the other side....... so using thread compound on the 14mm rear mounting bolts, and reconnecting the brake hose. this job is done for today.
happy with the result, looks factory fresh. -Total cost? $170 (plus paint.and grease).
Next up, Front replacement and bleeding brakes 101.
