DIY: Remove stock abs/vsc master cylinder ---> Install power brake booster & master
My disclaimer: this may not be 100% complete as some fabbing/creativity is involved. Do this at your own risk. I am not liable for any reason if you attempt this.
This is what i did to remove the entire ABS/VSC/TRAC system out of my 03 GS300.
parts i used:
Wilwood prop valve
3/16 compression tee's
new gaskets
new nuts with built in lock washers
the booster and master cylinder are from a 2000 Toyota Avalon. The booster bolt pattern is identical to the GS, so no drilling/modifying/hacking up the firewall. Help from a friend at Toyota for that tip!
1. remove all fuses, relays, buzzer, abs/vsc ecu
- remove 3 relays next to the unit
- remove abs ecu under dash
- remove buzzer next to ecu under dash
- remove 100a fuse next to battery (yellow circle)
- remove 40a fuse next to battery (grey circle)
2. remove stock unit
-unplug all harnesses to the unit
- remove bolt betwen pedal and booster
- remove 4 bolts under dash at pedal assembly
- remove 2 front lines from unit
- remove 2 rear lines from unit
carefully remove the whiole unit
3. install new booster/master
- install booster alone with gasket and nuts.
- install master cyl with gasket and tighten
- measure distance and make a spaces to thread on booster to attach to pedal
4. new lines
- cut, then crimp the lines inverted double flare the old lines to size and length
OR get stainless lines made
- put the 2 rears into a Tee and then to willwood prop valve OUT
- put the wilwood IN to the master furthest away from the firewall
- put the front lines into a Tee and then to the master closest to firewall
- bleed the lines and follow wilwoods instructions to set and test and dial in the prop valve. BE CAREFUL AND UNDERSTAND HOW IT WORKS BEFORE YOU GO ADJUSTING IT.
