I need to rebuild my slave clutch cylinder and thought I might as well rebuild the master as well. I saw the rebuild kits on Mazdatrix. Has anyone done this rebuild?

Jay Kim

 

Don't rebuild them. They'll fail again quickly. Just go with a remanufactured assembly, they are always priced reasonably, and guaranteed not to leak.

Ditto on what Sean said. I rebuilt mine last week and it still wasnt right. Got a reman. master from Autozone for like 72 bucks. Dont get the rebuild, it'll cost you more in the long run.

I beg to difer, and I have discussed this many a time on this board. but IF you rebuild it corectly it is as good as a new one. You MUST clean thep parts up very well. make sure there is no rust, or NO pitting in the cylinder chambers clean off ANY inperfections. If you do all this they will last another lifetime for you. I have always rebuilt and nver replaced do to the huge cost difference. And I am yet to have any of them fail on me. Clutch master from autozone $130.00, Slave=$72.00

rebuld kits $34.00 for both! you do the math.

 

Rebuild them. I rebuilt both master and slave for about $15 total. That was over a year ago and mine rx is my daily driver.

Like has been said you have to keep it all clean and do a good job or it won't last. It isn't all that hard and for so little money it is worth a try.

 

Clutch Master cylinder is $65 and the slave cylinder is $48 from Mazdatrix. I guess I could try the rebuilding first, but then again I risk not getting it right. that's about $30 down the drain that I could've used getting the reman ones to begin with. Man...decision decision....

Rebuilding works if the bore is good. Just clean the bore, check it, polish it, clean it good. If it looks good lube it with brake fluid and assemble the kit.

 

i just got a new one $70 no problems so far

 

Rebuilding is easy and reliable if done correctly.See Rpeck's comments above.Other tips:always clean with methanol(methyl hydrate),air blow dry if possible,use a brake hone tool to clean up any corrosion in the bore.If you do not want to do it yourself,I will sell you a rebuilt M/C for $30 plus $7 shipping and I will guarantee it not to leak.

 

What if it leaks? Then I gotta pay my mechanic to uninstall and then install another one. Do you have a Slave Cylinder as well?

Jay Kim

 

Pay the mechanic!!!?? It is easy. You will spend more time sitting in the waiting room waiting for them to look at your car then you would doing it yourself. Well may longer if you aren't used to working on stuff. but not much.

I still work on my car mostly cuz it's faster and I don't have people screwing it up.

 

At my local Autozone they are only 45 and 40 for the master and slave - ans it does perform much better than the rebuilt ones that I did correctly before. Much stronger units - no notchiness in the shifter now at all.

 

Would malfunctioning master or slave cylinders have anything to do with my engagement point? or how my tranny makes a noise like the throw-out bearing is bad?

I just got my clutch and put about 1000 miles on it.

Jay Kim

 

I only have one spare slave which I keep for myself.As far as the noises--it depends.If the hydraulics are marginal it might affect the engagement point and so gear crunching could result.If there is throwout bearing noise maybe your ace mechanics did not clean and lube the input shaft when they installed the new clutch.
Engagement point can be adjusted by adjusting the rod on the master cylinder--your ace mechanic should have checked that after installing the new clutch.

 

Well, I have to eat **** on this one... I pulled this out of the grave to correct myself. I talk about how great rebuilding the clutch parts is & how much money I saved.

Well I had to put a new slave cylinder in my N/A today .. the rebuild lasted about 6 months.

Word to the wise ... replace them don't rebuild them, will save you alot of headaches & time later.

It might also save you from having to take your motorcycle to work on a 95 degree day like I had to do

 

I have to commend you on your honesty and ability to admit when wrong. You be a better man than I.

 

Nice that you posted the results.

Wonder what you did different than me. I rebuilt the slave and master at the same time and I think I am up to 2 years on them now. Car is a daily driver too.

Now my driveshaft rebuild....that's not turning out as well =(

 

I think that rebuilding them is okay...but if you have the money to replace it...go for it!

 

Ya I have had sucsess with rebuilt ones in the past. On other cars besides RX's... this was my first attempt with a RX rebuild. It really could have been anything .. the cylinder might just have been worn past the point of a rebuild. It did last 6 months. but it should have lasted a few years. Life goes on .. I just thought I would share.
