Help! What brake options are available for S30 Z cars?


Recommended Posts

Hi guys

 

I have a sebuild set of 240sx calipers

and a pair of non vented 300zx rotors.

 

Now i want to buy the Modern Motorsports brackets but i cant get in touch with Ross or someone off that website.

It there some kind of other solution to use these parts? or another supplier with those brackets?

 

Please help because i already have those parts ready to be placed and already cut and removed my backdrum parts.

 

( i know it was stupid but i did it when i had the brackets. But unfortunately it were brackets for maxima calipers )

Has anyone come up with a source for the 79 - 81 master cylinder ??? I have the Toyota 4 piston with stock system on 78 z

 

it works well but I have increased pedal travel. Any other ideas would be appreciated.

Didnt want to start a new thread and figured this info would be useful.

I have searched and couldnt find the answer to this...

 

I have a 72 240z which i am completely redoing from the ground up.

For the brakes i am doing s12w vented front setup and for the rears maxima disc conversion.

I have already bought the wilwood 1" brake master, and got stainless steel brake lines.

The only thing left is the brake booster. From what ive searched, the later year boosters and the 2+2

booster are the upgrade. The booster i pulled off my Z is in good working condition, but its the smallest one

that came on the Z. I got the bigger 73'+ booster thinking it would fit with just new holes in the firewall,

but have since realize that the booster itself seems like it would cover the clutch master.

I would definitely like to upgrade the brake booster while everything is out and accessible.

 

Any info on how to make this work or what i could use as an alternative upgrade would be appreciated!

Search the brake section. There are several threads that cover booster upgrade fitment solutions and the Wilwood 1 inch MC install. Start with the very first thread in the brake section.

Not sure where you found or know of several threads regarding the booster upgrades. I have searched and read through all the brake FAQs and searched all the topics in the brake section, none of them covered what im asking. I have already done the modifications to the wilwood master, i dont need help with that, my question was what can i do to upgrade just my brake booster. I am aware that the later year s30s had a different bolt pattern on the brake boosters and firewall, which is why the s130 boosters fit. I have a 72' 240z with the narrower and smaller booster, so i can not use the s130 booster, or even the 73' and later boosters as they interfere with the clutch master.

 

If you can point me to the threads you are referring to that'd be great.

I used a 280Z eight-inch booster when I did my Wilwood 1 inch swap to compensate for the additional effort caused by the larger bore Wilwood MC.

 

 

 

That said, below is a list of threads I researched when I did my swap last October. Also, search at ClassicZ Car site.

 

 

 

There are other variables that determine the largest diameter booster you can use such as the size of the clutch MC. You will need to adjust the MC push rod when you swap the MC and booster. Ultimately, you wiil have to measure and spend some time planning the swap.

Reading through all 20 pages of the evolution of this thread, I'd like to venture an opinion from the viewpoint of a fellow who had an interminable garage-queen project, which is slowly venturing out into preliminary testing. These are 40-year old cars. In many cases, we have 20-year old tires and brake pads. Some of our calipers have seized, to the point that the car is difficult to push on level-ground. Even modest application of the brakes from 20 mph causes the car to dart laterally. It's blatantly unsafe and requires through refurbishment.

 

The point is, if you're going to completely go through the braking system, and are not planning on campaigning the cars in a class where rules dictate usage of particular brakes, is it worthwhile to attempt a stock refresh, or to go for an upgrade? I don't need fancy brakes, and don't want the excess weight. I neither have the skill, the experience, the access to venues or the panache to drive my car at 9/10ths. I'll be driving it at 3/10ths and calling it "high performance". But I do need to fix my brakes so as not to be a danger to myself or to fellow drivers on the street. So I ask again: why not use the present opportunity to upgrade the braking system? But the countervailing point is: why goldplate the thing? The proverbial happy-medium is the obvious solution, but it gets complicated because modifying/replacing one set of components triggers a cascade of newly necessary changes.

I don't know the answer to this one. Michael is correct from a totally pragmatic point of view. That said, the Mustang SV0 stuff is pretty cheap if you can swing the swap to five lug, which included a commitment to new wheels. I'd put the Mustang stuff up against anything heavier duty.

I have a question to see if anyone ran into this problem with the brake swap. after I complete the swap and when I blead the brakes I notice the 240sx real calipers would leak brake fluid either on the right or left side. I even took that back to Napa and got another pair of new ones and it would still happen. Once i adjusted the proportion value it didnt it not more but it seems my front brakes dont stop on a dime they work but dont grip hard enough. Now I did rellize I have to change my brake booster cause it seemed that when I brake my engine drops idle real low. Now if the booster having a valcume leak would theat effect my brakes gripping hard enough? any one have any input?

I sure do appreciate that the Toyota S12w and the the 280zx rear caliper both allow changing the pads without removing the caliper.

Not all cars do that and if a person were swapping pads a lot this is a big help.

The price and serviceabillity almost make up for the weight and bias penalty.

Has anyone attempted to use brembo brakes?? I saw a nice set of evo lancer brakes for around 800. Im tempted to pick up a set and fab my own mounting brackets. Would it just be a matter of choosing the right suspension parts, wheels and fabbing some brackets??
