Default Having trouble with replacing my rotors on a 2007 WRX.

So I was able to replace my brake pads just fine. My problem is taking off the calipers to access taking off my rotors. Am I doing more than I need to? What i'm doing is trying to take off the bolts behind the calipers so I can take them off and access the rotor. The problem with that is the bolts are on suuuper tight, and its not just that. I don't have any room behind the caliper to fit a torque wrench in and take the bolts off. If anyone can provide tips that'd be helpful. All the shops around Vegas are charging $95+ just to install rotors.

Don't know what to say, but get more on those bolts. They can get rough with being exposed and out there and pick up some corrosion.

PB Blaster / Liquid Wrench or whatever your favorite penetrant is, then get a combo wrench on it and whack that with a deadblow hammer if you need to.

This just happened to me not too long ago on my 2006 wrx. According to the dealership this is a common occurrence with the 4pot calipers Only the fronts, the back 2pots do not have the issue. I just used tons of PB and cranked the wheel all the way so I was able to get a small pipe on the end of my wrench. Just a tip, use a 6 point wrench if you can, the bolts are extremely soft for some reason and a 12 point may murder the head. I ended up braking the bolts on the driver's side and had to attempt to pound the caliper away from the mounting bracket which lead to me braking the caliper I reinstalled the bolts with some anti-seize in hopes that this would not happen again and torqued to specs. Good luck with yours! hope it goes much better than it did for me haha.

PB blaster, breaker bar and mallet if needed then, use anti seize putting it back together so you don't have an issue taking them off next time

Why would you use a torque wrench to remove a bolt?

And one combination wrench stuck on the other, or hitting the wrench with the hammer, or just going and getting a breaker bar would all probably work.

he probably recommended this because a torque wrench is as long as a lypical breaker bar. however, i would never use an expensive torque wrench to break free a stuck nut/bolt. i would rather risk a normal breaker bar/pipe combo.

I had to turn the wheel and use a pipe on a bresker bar. It may be a silly question but are you turning it the right way

Use carburetor cleaner instead of the PB blaster. It contains an acid that is there to eat away varnish and crap off of carbs and will penetrate faster. Take a small ball peen hammer after spraying the bolts, and smack them directly on the head of the bolt several times-straight in the direction that they are threaded in. This helps loosen the threads inside of the threaded hole. Then, use a breaker bar, 6 point socket and pull to loosen. If they still don't want to come lose, then try to tighten the bolt a tiny bit. Pull on it to loosen again and keep going-tighten and loosen, until it comes loose. A broken bolt is just as much pain in the ass as it sounds so do whatever you can to NOT break them.

Remember: When working on Subaru, learn two words very well-ANTI SEIZE ! !

Use it on EVERY bolt you ever put back in.

Step 1 don't use a torque wrench to loosen things
Step 2 get a proper breaker bar. I got mine off by standing on 18" breaker bar.

Make sure you're turning the right way. For the driver side you should be going towards the ground.

It might help to take the lower bolt off strut, it won't affect your camber when you put it back.

Or perhaps he doesn't know the proper names for tools? I have heard people call a breaker bar a torque wrench before


There is also a chance that i have far to much faith in humanity.....

Nothing wrong with using a torque wrench to remove things per se, but the head of the torque wrench is large and may hit the strut bolts or brake line, as well as you may damage the torque wrench itself.

Go to harbor freight and buy yourself a breaker bar, it has no head and swivels so it can fit into tight places, as well as being able to turn from different angles. SHould be around $10.

Then jack up the car and take off both front wheels. Turn the steering wheel full left when working on the left side and full right when working on the right side, this sometimes helps to give you more room.

I just did the brakes on my brothers EVO X yesterday and his brakes are even bigger than yours. It was a biotch to break the top bolt loose, but when i threw on the breaker bar, it went super easy.
