Vn Master Cylinder

[kangaroosa]

I have installed a VN V8 master cylinder into my KE30. I forgot to ask which outlets are for front and rear. Its too late to call now, so is there anyone that can answer this for me, and possibly post a pic.

 

I have to get these brake lines bent into shape and then sent off to have the correct threaded ends on them....preferably tonight or tommorow as the christmas holidays is quickly approaching.

[oh what a nissan feeling!]

The two side by side underneath at the front of the cylinder are the front wheels.

The one on the right closer to the booster is the rears, it takes a bigger spanner as well.

 

are you aware of the need for an extra small spacer inside of where the shaft from the booster fits in?

The vn commo cylinder is about 4mm deeper (from memory) then the ke55 one.

Ok, so i have to run lines from both wheel arches to the master cylinder, as opposed to the one line from the diverter block for the fronts.

 

I have a fitting on the very front of the master (Radiator side). Is this for the fronts that you mentioned. There is also another on the passenger side of the master, but tucked under. Hopefully these are the fronts your talking about.

The larger one nearest the firewall is larger diam thread, so therefor i understand that its the rear one.

 

I wasnt told about the need for a spacer. The brake guy mentioned something about measuring it up to make sure it all fits nicely. In the end i bought a new booster and master, so i'm not sure if he adjusted anything to suit as he was going to do when he was reconditioning it.

 

Any pics or more info on the spacer would be great please.

Yep, that it, the block goes to the bin.

I'm pretty sure youre talking about the thread for the tower brace. this is where you mount a bracket to prevent firewall flex.

The two in the photo underneath at the front are front left and right.

 

For the spacer, put a small screwdriver down the hole where the master cylinder would push,

measure this to the face of the cylinder.

Do the same to the ke55 cylinder, and you will find the vn master cylinder is lightly deeper.

To correct this depth i drilled the end of a bolt, to creat a dip for the shaft to sit in,

and then cut the end off the bolt to the length needed.

I then used a strong glue to glue this small piece down in the hole.

This is needed to get a good pedal feel, the brakes would still be ok without it, but not the best.

 

hope this helps

 

 

My explanation probably sux, i can probably do pics if this can't be understood?

Ok, first of all Thanks for the pic. I just bent my existing lines into the shape i need, but he will have to duplicate them with the required fittings. Luckily, thanks to your pic I noticed i have stuffed up. I ran a line to the front hole where the brace should be, instead of running it underneath. I totally missed that second hole underneath.

 

I spoke to the brake bloke today and he said that its fine to run one line off the master for the front brakes, and run it straight into the diverter block. As for the spare hole....just plug it with a bolt.

 

Apparently my master cylinder and booster were built to suit each other. They made a new piston for the master to suit the booster, so the spacer is not required.

 

Thanks again for your help.
