Brake caliper help

So I have had the often discussed E Brake squeal since installing my Nitron coilovers. Noise is on the driver side and I am certain it is E break related as it goes away when I lightly lift up on the E break.

Today I decided to finally mess with it as I have been embarrassed more than once driving around with it squeaking. I noticed one of my bolts on either side was loose enough that I could tighten by hand, so I lightly tightened both sides with a torque wrench but then the car was literally stuck in place so I backed the bolts to just hand tightened.

I took the car for a drive around the neighborhood and the noise is gone but I swear it feels like the E break is ever so lightly applied (shows off on dash). Obviously I do not want to drive

around with the e brake lightly on but I canít imagine having 4 bolts (2 in pic below) any lighter than hand tightened.

Does anyone have the procedure to putting the brake caliper back together that may provide direction as to how tight they should be?

From what I remember you have to:
1. remove the caliper
2. back or remove the set screw from underneath
3. push the piston back in by rotating it
4. re-align the set screw with the slot
5. put the pads back on and re-install the caliper.
6 pulling on the hand brake will re-adjust the hand brake

That all I did when I changed my pads last year

Handyman2009 is correct and I suspect someone didn't tighten the bolt because they did not know to retract the mechanical piston. Retract the piston before tightening the bolts.

Thanks guys, I was the who installed them and believe I retracted the piston (not 100% certain as it was over a year ago). The e brake would not have worked though had I not retracted prior to tightening, correct? It has been working fine, just the light squeal at times.

Perhaps this may help, in the below picture, do you have the same gap between both sides of the caliper? Thanks!

I will check mine tonight but I don't believe that I have any gap between the front and the back part of the caliper. I will get back to you later tonight when I am home

Appreciate it, that should help to determine if there is a problem then with mine. Probably hard to tell in pic but where aarow is pointing is largest gap (roughly 3-4mm). Other side is about 2mm and neither of the e brake caliper sides are touching. Thanks!

That gap isn't right -- both sides should be tight together.

BTW -- Porterfield e-brake pads stopped the squeaking for me.

The two halves of the e-brake caliper on my Vantage do not have a gap.

Pretty hard to take pictures with the wheels on the car but you can see that there is no gap... you probably didn't push back the piston far enough. Good luck with the fix

Thanks for all the replies, pictures and link. I just can't believe I've been driving around like this for over a year engaging the parking brake often, and never having an issue!

I have a staple in my brand new PS4S so I have to take my wheel off anyways and will give this a go in the next two weeks. Seems like a major pain in the butt to get right!

Not to steal the thread, but is a tool required to wind in the pistons on the e-brake caliper? If so, does anyone have a brand name?

Thanks

not stealing at all, I too would love a brand/link!

I believe that I only use long nose pliers and it is very easy to spin

Thanks Handyman. I wondered. When I did rear brake pads, I purchased a tool to retract the brake pistons. They went back in so easily that I returned the unopened tool. Thanks to Redpants Rich for the tech tip.

My car is a 2011 V8V S roadster. I recently put in a new battery and came up with a little trick that may help someone else. Check my post titled "the battery is in". Thanks to everyone on this site
