Brake Troubleshooting

[love ke70]

nope nope nope

you have air trapped in your master cylinder.
you need to bench bleed it, then install
all your woes will be gone

trust me, same issue i had in a ke70 when i had the system empty then put the ra60 and twin spot alfa rear calipers on.

if a ke70 MC can power them, the starlet one can power your piss all larger starlet brakes

Well the guys down at ABS bleed my brakes too and that didnt make any difference either, so im still saying its the MC.

Whats bench bleeding though? I've never heard of it.

same applies for when the MC has been drained, im assuming this one has, as most people dont think to clamp theyre brake lines when taking calipers off...

i got my mc bled when i took it to b&r brakes (a toymods sponsor)

they just disconnected the brakes likes from the master cylinder and pumped fluid straight out of the mc.

actually they didnt disconnect the lines completely, just losenes one at a time until the fluid can escape.

they sprayed water on the areas around the mc first to protect everything and gave it a good rinse afterwards also...

well yes, that would work

thanks guys, i will be sure to bench bleed the new master cyl before i put it on

Also has anyone thought of checking the proportioning valve?

[love ke70]

why would that be making the pedal hit the floor?
serious question, never dealt with propportioning valves before...
