The only problem I noticed was that the pedal was pretty mushy. After doing a complete bleed through it didn't resolve the issue. After jacking the truck up, I noticed the back brakes weren't working at all! This was after I had rear ended some dork that had stopped in the left lane on I-45 in Houston cause they were gonna miss their turnoff. <img src="/forums/images/graemlins/frown.gif" alt="" /> At least the truck was still driveable. I guess I hit the car in front of me at around 10mph or so?

So the first thing I did was replace the master cylinder since Toyota wanted about $70 fer the kit and that wouldn't have been a guarantee that it would've fixed the problem. So I picked up a master cylinder from AutoZone (ordered and received the next day at the store) which was an Aisin aluminum one that had the number 1 stamped on it. So I guess it's a 1" bore...seems to work pretty good.

The pedal feel didn't change at all as it was still mushy but I wasn't able to bottom it out on the floorboard. This was after a complete bench bleed and system bleed. I thought about the entire system all night before I came to the conclusion about the LSPV. So the next day, I took off the rod and rubber boot from the LSPV to see if there were any problems I could see from the outside. None that was visible...so I pumped the pedal and then banged on the LSPV a few times to see it that would change anything. The pedal went to the floor after all the "attitude adjustments" and I knew something had changed. Bled the LSPV first to make sure I was gitting a good flow up to that point. Ended up bleeding a ton of air from the left rear brake to the point where it was sputtering out of the bleeder valve. The pedal finally firmed up and I bled out the rest of the system. I then put the rod and rubber boot back on the LSPV.

If I had a spare one to work from, I'd be willing to tear it apart and document all the various pieces and the condition they were in as well as the cleaning. I'm really curious about that C-clip though... <img src="/forums/images/graemlins/wink.gif" alt="" /> Not sure I'd be willing to put some lubricant in there to free it up...it might send particles downstream to git clogged up somewhere else.
