I was in the middle of installing a new Sunny master cylinder on my kb10 yesterday when I realised the pushrod between the master cylinder and the brake pedal is shorter than it needs to be.

When I realised this, I vaugly remember that there is a pushrod change required to make the system work.

Can someone tell me if its the sunny pushrod rquired, or can I rob one from any other model?? Or can you buy these new from a brake place etc. ???

Thanks.

just make one of your own.much, much cheaper & less headach trying to find one.

daniel,are you putting a vaccum booster on the 1000,or just replacing the master cylinder?when i put that 13/16's master cylinder on that car,i used the original rod which came with the previous master cylinder,which was a 3/4
one,probably from a 120y.you could try finding
the rod from an early 120y & use the bit that goes around the brake pedal.the few times i drove the car before selling the car to frank,it seemed the brake pedal was ok.if you're putting a booster on it,again find a boosted 120y,which has a threaded adjustment on the end.

I don't think there is a rod that bolts straight in
The original 11/16" master has a captive pushrod and the sunny and the 3/4" unit are normally supposed to go on boosters so have different rod depths on the piston
I use a rod from a toyota and modify it to use on my 1000 kits when I use the sunny master
I can send you one if you give me a postal address

Cheers
Neil

B310GX: Sorry for the confusion! I should have mentioned that I'm building a new KB10 for road use. The race car is going like a trooper - just got first and third places in the nsw supersprint champ.

I've removed the original master cylinder and I'm installing a sunny master cylinder (the larger one). Basically copying the race car setup. Only the pushrod is now too short to work properly.

Are the 120Y pushrods a solution to this problem?? I guess the sunny pushrod should fit, that is unless the pedal geometery is different somehow.

Dattoman_1000: Thanks mate. If I can't find a pushrod locally and cheaply I might get you to send me one. What do you charge for one??

...and I won't be running a brake booster!

For you
$0.00 plus GST
= $0.00

If you need one

Quote: Well don't keep us in suspense too long. We need photographic evidence that this car actually exists, along with some technical details.

If it runs as well as your race coupe, i had better keep out of your way.

Well geez, can't beat that offer. I wouldn't mind getting one of your modified rods then Neil. Although the master cylinder I've purchased is a 13/16" unit (20.64mm from memory). I'm wondering if it is different to the 11/16" unit you've mentioned.

This unit of mine is also a captive rod type using a circlip. The original KB10 pushrod fits in beautifully, its just too short. Do you need a pic of this unit ???

If you think you can make a rod to fit, then send one over !!! I'll keep this site up-to-date with the result.

Dodgeman: Ok, I'll get too it...

I bought this car off ebay cause it was a good straight little car. Working full time and doing uni full time as well keeps me really busy. I'm also trying to save for our wedding in may next year, so money isn't free-flowing at the moment.

I've decided the first part of this project will be to get the brakes working well. I'm picking up a R31 rear end in sydney hopefully tomorrow. Disks are planned for the front as well, but I'm not there yet.

This car will be road registered and a test bed for new motors for the race car. Mick and myself want to muck around with efi and fine tuning the intake and exhaust setup for the race car. It's too hard to do it at the track and who can afford dyno time each fortnight to try stuff!!
