so I recently snapped my master cylinder bleeder screw...and since then..i managed to hand drilled a hole in the screw and tried to use easy out. However, apparently, I torqued it in with so much force that, in the end, reverse torquing did not work..it just kept losing grip. I even tried heating up the unit to about 70 degree and then quickly froze the hole that i drilled out. All failed....

what other ways are there??

If i am going to replace my master cylinder...how much will it cost at dealer?

how hard is it?

 

Wow, that sucks. I'd try way more than that before buying a new one. Try to find reversed pitch drill bits. or drill same dia. hole and retap for oversize bolt...and so on. you should be able to grab it that way.

 

hjahah hopeless now.
i just removed the master cylinder..and so i get the space i needed to work on the screw with the extractor..and the extractor broke..
LOL
so new one it is...

guys.

is there any trick in putting it back on??
like anything i need to know

 

can someone give me a part number for 04 rx8 brake master cylinder. I just want the Aluminum unit not the resovior.
I found something like: F1534343ZA---is there a difference between the DSC ones and the non DSC ones.
PLEASE LET ME KNOW

btw.
When I was taking off the master cylinder, there is a hose right beside a electric connector. what does the hose do???

 

F1514343ZA = cars without DSC
F1534343ZA = cars with DSC

You are probably referring to the hose that runs to the clutch's master cylinder just to the right of the brake booster.

 

so...err..what does that mean?? when you say right, you mean driver side??

basically, I would like to know the right way of reconstructing it.

my idea is
-put everything back and bleed brake

but what is the right way?

is there anything i need to watch for?

THANKS FOR THE PART NUMBER

 

Yes... the driver's side

The RIGHT way is to bleed in this order:
MC, passenger rear, driver rear, passenger front, driver front, MC
Obviously... you'll be skipping the MC bleeding.

If the braking is "spongy" after bleeding, air is still in the line you'll need to bleed the MC too.

No problem.

 

Won't you need to bleed the clutch slave cylinder also?

 

???
Ok i am not sure what's going on now. I didn't even know that the cluth has a hose that goes to the master cylinder.

So I would like to know
A) why does the clutch have a hose going to the master cylinder??

B) how do i need to deal with the clutch hose part when putting it back.

 

Hydraulic clutch...it shares fluid with the brakes.

You may have to "bench bleed" the master cylinder before putting it in...not sure about RX-8, but it's typical.

Do you have the shop manual? If not, you can download it from

Good luck.

I see your point alnielsen, I was going off of just the brake bleeding order.
But messing with the master cylinder the way he is, it probably would be a good idea to bleed the clutch too.

Because the brake system shares its hydraulic fluid with the clutch.

Just make sure to bleed to the slave cylinder when you're done.
It can be a PITA to reach because its behind the oil filter on top of the transmission.

 

so to fully bleed my system and safe.

I should start of with
MS, SS, Passenger R, Driver R, PF, RF, MS again.

Does that sound good??

 

I've always done the slave cylinder last (mainly because I hate that the most).
As long as the SS is performed sometime after the MC, it shouldn't matter when you do it.
