Hello,
I started replacing break pads on rear, but it's really hard to push those piston back in. When I had research through this, I had to push while turning it in clockwise. It was very difficult for me to push and turn because my needlenose kept play itself. Piston seems like worn off. Does it suppose to be this difficult to turn it? Piston is so hard, and it barely move at all. I spend more than hour to push it back in. I couldn't finish the other wheel because of time I had spent on pushing the piston back. A lot of people mentioned about C-Clamp.
When do you use it? Right after you take a caliper off? Does C-clamp do nothing but the prevention of piston coming out from pressure?
Don't you still have to push them in since new pads will be thinker than old one? I spent roughly 3 hours in one wheel, and I am looking foward to finish the other wheel. Just curious, how do those mechanics do the break job so fast? Is there somekind of special tool that can be replacement of needlenose? Thanks in advance..

 

I used needle-nosed pliers and light pressure from a C-clamp. I found that twisting and adding a small amount of pressure in combination did the job in the most efficient way. If you didn't take off the cap from your brake fluid reservoir, do that too.

 

I didn't have to push in at all, just turn clockwise. There is a tool for this by the way but I was able to do it with pliers.

 

This is true. Go and buy the tool. Its around $8 and will save you lots of time!

 

I sprayed some wd-40 under the rubber sleave and it screwed in very nicely.

 

if it's really jammed, it might be like my rear calipers were... frozen. i had to go buy new rear calipers.

 

So..just to go to any shop, and ask for C-clamp? It comes with standard size for break job? Thanks

 

I tried to do this left caliper today morning.. Problem..I can't even unscrew bottom bolt out from the caliper. It ruined my socket wrench as well as bolt itself. Of course, I used WD-40 from beginning. After pulling and pushing for 40 min, I decided to ask you another advice for this.
What's the best way to remove stuck bolt?

What size is this bolt? According to my socket wrench, I used 9/16". Does it come with standard length? Can I buy this bolt from Home Depot?

 

It is a special brake piston turning tool which attaches to a 3/8" ratchet. I had the same problem as you, and using it was the only way I could put my piston back in. It looks like this:

u used a 9/16"?? the is a japaneese car..use standard not metric...and there prolly is gonna be no easy way to get it out, so just pray you can get it with something to avoid having to get it torched off

 

Yeah, I had the same problem and bought the tool that is pictured above. the silver thing. It is a life saver! Really inexpensice also. Hope that helped.

 

yea its always hard for me too. the first time i did it i made a mistake and left the e brake up then i made a mistake and left the friggin car in first gear lol. I actually shredded that tool trying to turn it and got an ill work out from it. I bought a new one wit my recent job and did the job a lot faster but still took some time. I hate doing the back brakes, its such a PITA just cause of this caliper BS....

 

wasting time with wd-40, need to get a can of
PB BLASTER, can get it from walmart this stuff is the real deal

 

Pb blaster is better then wd40 for lubrication, but for lubricating the caliper piston seals a bit, i`d use brake fluid. Other solvents or petroleum base lubricants may harm - will harm - rubber seals.

 

I had a terrible time doing my rear breaks. I had to remove the caliper, torque member, and rotor; then reinstall some of it. I had the caliper held on with one bolt so it could be rotated out and then I could push and pull that ****. I used my crimpimg tool to turn the piston.

Needles to say it was not cool, and i should have bought the proper tool.

 

I think you mean use metric not standard ( 9/16" is standard) I believe it's a 12mm or 14mm. No you can't pick it up at Home Depot, you need factory replacement, good luck

 

ahhh, to live in canada

 

Ive got one of those also, makes it so much easier.

 

You are going to have to get the bolt at a Nissan dealer. It is a special bolt. Don't know if you go the bolt out yet or not from your posting or how badly it is damaged. You may have to heat the bolt up red hot(propane is not hot enough - in most cases) and it should give when using a wrench. Of course your being a novice I must stress using extreme caution since you can also destroy other parts such as the seals and you could end up with a real mess. I had a similar problem about 5 years ago and I had to take it to the local PepBoys to have the bolt removed (the head of the bole broke off). It was done in less than a half hour and they also had to go to Nissan for the bolt. The C clamp will not work on the piston. It has to be turned clockwise in. The little tool that snaps on a 3/8" drive is a lifesaver. Also, the notch on the piston goes straight up when reinstalling the caliper. If you do not line it up correctly, you'll end up with more problems like a dragging brake. Have fun. It is a learning experience.
