On a scale from 1-10, how stupid is this idea?

[Dirtyl3um]

okay SO, i have a 93 240 and my sister has a 91, she bought it from some guy and he told her the back brake pads needed to be replaced, and then she would be off and running, well the douche didnt tell her that he effed up both rear calipers and the pads needed to be replaced and the master cylinder was bad. So...

I replaced the master cylinder and began to bleed the brakes. This is when i found out that the calipers are skrewed up. The problem is, the dust cover over the pistons is not there, and apparently theres a small pin sized hole that squirts brake fluid out if the dust cover is not present (what the hell is that for?) well, other than the fluid coming out that small hole, (not the bleeder valve, its a hole on the actual piston) the calipers work fine, the pistons still put pressure on the pads.

How stupid would it be to jb weld those holes shut? has anyone tried it? and what the hell do they do? Are there other calipers that will fit the old pads that would be cheaper than the 240sx ones? Ive called around and there gonna b 60 bucks a piece, and jb weld is like a 5 dollar container...

Input?

I have never noticed a hole where fluid should be shooting out. I Don't have my dust covers on and I have never seen fluid coming out. I don't really know whats goin on with yours.

[MastaYu]

Jb weld I don't think that's a good idea

[godzilla34]

the hole allows for lubrication, i wouldnt jb it. just keep it clean and install new gaskets on it. not to hard to do and if you do it right they will be as good as new. but the hole is to keep the boot from cracking and keeps the inner gasket closest to the top of the piston lubed up.

[Dirtyl3um]

So why is it leaking? Now that i think about it i may have to buy new calipers altogether. The brake pads that were previously on it were so thin, they were worn way beyond the point of when they should have been changed. there at about 1/8 -1/16 in deep scores in the rotor from the metal underneath the pad. Is it possible that the pistons were pushed beyond the point they are supposed to be and that is why there is a fricking jet stream shooting out?

Ummmm 15 Just rebuild them. Your brakes shouldn't be leaking anything. Don't be a cheap ***, the rebuild kits are cheap and the rear calipers are too easy to find anyway. Just do it right.

[DriftToy]

JB weld??? Do you know how much pressure is there when your brakes are applied? 11 on the bad scale!

[twistedsymphony]

with the amount of people who swap in 300zx calipers good used calipers should be cheap money. Rebuild kits are cheap too... we're talking ~$30 (I would be shocked if used calipers would cost you much more than that).

brakes are a safety issue... if you want to put your life in the hands of jb weld, that's your decision, personally I'd find someone with a used set of calipers.

Not to mention your sister's life...!!!

[wingFeather]

Replace the calipers... they aren't expensive & priceless compared to her life!!!

[Vegascorbin]

Wow! You must really not like your sister.

Go with the rebuild kit. If you don't think a rebuild kit will fix the problem then get pictures and let us see exactly what hole you are refering to.

[240sxbuffy]

WAKE UP YOU ARE TALKING ABOUT YOUR BRAKES !!!!!!!!!!!!!!!!!!!!! REPLACE THE CALIPERS BEFORE SOMEONE GETS HURT!!!!!!!!!!!!!!!!!!!!!!!!! THERE IS NO HOLE IN A CALIPER FOR LUBRCATION I AM A ASE CERTIFIED MASTER TECH I HAVE BEEN WORKING ON CARS FOR 27 YEARS THERE IS NO LUBE HOLE ON A CALIPER !!! IF THE DUST BOOT IS MISSING THEN THE CALIPER WILL SEIZE IF ITS LEAKING FLUID THEN ITS NOT WORKING AND DEATH IS A REAL POSSIBILITY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Encryptshun]

Wow, easy there, buffy.

[NissaNassin1031]

fluids should never be squirting out, regardless of dust cover. replace all the boots and whatnot with a rebuild kit and make sure the hoses are all good. rebuild kits are pretty cheap and usually you don't need to replace the whole caliper, just the rubber and stuff that does go bad. btw, I'd say 8 to be honest. You don't really even know what the problem is obviously, putting a dust cover would not fix that leak, it'll just hide the leak a little.

1-10

10 lol time for a rebuild, or swap some 300zx brakes on

[Rin5]

Wow, easy there, buffy.

or opt for bedrock brakes...

easy install...

step 1: drill big a$$ hole where your feet rest.

jk jk XD

I have a set of OEM calipers off of my S14 that I will sell you cheap. PM me if you're interested.

[Encryptshun]

Look at the big brain on Claude.

:facepalm

[Ilvemynissan]

LOL

Ok, maybe that was a little opportunistic of me.

[the technican]

aww man for the cost of rebuilt calipers it not worth taking a risk with some shady tree engineering do it the way you know it should be

not to be a buzz kill , but ive rebuilt 4 of them. all rears, 2 from an s13 chassi and 2 from an s14 chassi. and yes they all had those holes in them and hes not talking in the caliper hes talking about the piston inside the caliper. its rubber so it will deteriate, ever since ive rebuilt them we havent had a problem since. and its been two years now...with heavy driving/ track running. if the walls are scored best bet is to buy a used set, and depending on the condition of it might rebuild that one so all the sill's are good. or have them honed but if its badly scored new ones are a must. if you need pics of the holes i will send them to you just shoot me an email [email protected] but im not shooting down your experience or your service. just wanted to clerify what i said.after rereading it and rereading what i had posted it might not be for lub. might be a safty feature to keep you from driving. common sence tells you not to drive your car if you cant stop. (for myself)

[240sxbuffy]

Maybe And yes you can rebuild caliepers and it is quite easy however if someone is even asking about trying to JB weld something they have no bussiness try to rebuild an item as important as a brakes!! plane and simple.

You may be a ASE certified master tech but your spelling skills suck. No offense.

[godzilla34]

thats true but then again he posted it for advice. which means he is willing to learn about the system. when theres a leak somewhere, your natural reaction is to stop the leak. but by posting his idea he has saved his car and someone else's who has the same or similar problem, but doesnt want to post because he doesnt want to get flamed or get bad reputation for asking "noob" questions. i give props to those who ask questions like this, there isnt a dumb or a stupid/noob question, i think the only question thats stupid is a question that isnt asked. if theres a question ask it which is exactly what he did, and he got many answers for doing so.once again im not docking you or putting you down just want to shoot out my advice.

[g.i.joe]

Ive called around and there gonna b 60 bucks a piece, and jb weld is like a 5 dollar container...

Input?

5buck to kill a loved one or 60 tobe sure she's all good.... ???YOU do the math lol

[g.i.joe]

oh and i'm only trying 2 make you realize its safer to just swap out the bad brakes, really not tryin to be an ***hole bro! *(seriously)

[Red coupe]

with the amount of people who swap in 300zx calipers good used calipers should be cheap money. Rebuild kits are cheap too... we're talking ~$30 (I would be shocked if used calipers would cost you much more than that).

Not too many people do a swap on the rears though, as its a bit more involved...The rears don't do much braking anyways, and if I am not mistaken are on a different hydraulic circuit...

PSI may be high, but if its a pin hole sized hole the actual force on it will be much lower...

HOWEVER, I have heard of loaded calipers for pretty cheap. Don't JB weld the brakes just go fix it. Definitely a case of just do it right man.

[ramal]

just rebuild them. you don't want to play with your brakes and anything else you do will just require you to work on them again later.
