VS V6 twin turbo 4.2L stroker build thread

If I need different manifolds then so be it lol can't see why though.

Any ideas with the brakes??

 

[Bowen]

Ok, so I've done the vt brake conversion.
I changed the front rotors and callipers, and I put the vt booster and master cylinder in. I bled the brakes with new fluid and everything seemed perfect for a while. But after a bit of driving the brakes start locking on until I almost can't move it. Any ideas why this is happening? Have I missed anything?
Kinda need my car drivable lol

What do you mean by locking on? As in clamped against the rotor preventing it from turning? In essence dragging? Or the pedal doesn't reset?

 

[moocow]

As in slowly clamps to the rotor until I can hardly move the car and they don't fully let go until the car has been sitting for a few hours. After about 4 kilometres of forcing my car along today I got home and smoke was pouring off my brakes. Don't wanna do that again so I need to fix this lol

if the master cylinder doesnt fully return it will lock the brakes on when the fluid gets hot

 

[moocow]

I've had a thought. Do I need to relocate the hole that the pin connecting the push rod to the brake pedal goes through?

 

[BowTie]

Master cylinder breather hole?

Caliper seizing? Are both wheels locking?

 

[moocow]

Forgive me but breather hole?

All 4 are. I'm about to have a go at adjusting the push rod and then probably bleed them again to be sure.

 

[delcowizzid]

did you fit vt booster as well cause on vn i know you have to redrill the hole in the rod for the pedal

 

[moocow]

I did exactly that and it seems to have fixed it
Pedal is a little spongey so I'll bleed them on the weekend and see how they are. One I'm done I'll write up a guide I think.
