Rear Brembo brake upgrade on a Limited WK

Just installed a pair of 09 rear Brembo brake calipers on my WK. I got them from a local boneyard on an SRT that was already well picked through. I was also able to get one of the front knuckles/spindles for the future front Brembos. In the first pick you can see all the parts needed to do the rears. The backing plates are needed to give the calipers something to bolt onto. The rotors are different then the standard WKs being vented. I also put on rear SRT springs and sway bar, Bwoody end links and HD Bilsteins at the same time. Taking the rear rotors and hub bearings off was not too much of a problem for me but my good luck did not hold out for removing the old lower shock mount bolts or the old sway bar mounting bracket bolts. I had to invent new laws in physics to gain a force advantage over these in order to get them off. They were a bear! The whole thing took me about ten hours but I'm not a mechanic but a learn as I go garage wannabe. VERY PLEASED WITH THE TIGHTNESS I now feel in the ride due to the new shocks and SRT sway bar. I also like the look of the new four piston caliper Brembos. I know the color off set with my Deep Beryl Green Jeep is not very good but I still like them. I would certainly recommend this upgrade for anyone looking for a sportier look at the rear and less fade in braking. The springs dropped the rear about an inch and removed the rake from the stance. Some members leave it like this as they like the look. I still have to install the front Bilstein struts and SRT springs so the rake will be back as the front will drop an inch too. I was impressed how much a one inch drop effects the overall stance! Wasn't expecting it to be this noticable. Sorry it's in black and white. This was how my daughter's camera was set up and I didn't realise it until I put them up here. Kind of takes away from the look. Just imagine bright red calipers on a Deep beryl Green truck. I'm too lazy to do it all over again!

The calipers were $300 a piece with the brake hoses attached. Parts are typically more expensive up here in Canada. The calipers were in excellent condition as they appeared new in every way. The backing plates were $200 a piece and the rotors $150 for the pair. Not a cheap mod but certainly a "flashy" one. I will try to get color pictures up tomorrow as the black and white don't do them justice.

Thanks! I've been stiff as a board for the past two days. I could barely put my socks on this morning. Being in a crouched position pulling wrenches all day, and I'm not in the shape that I use to be, wasn't that great. As you guys know however, the mods are so much more satisfying when you do the work yourself. I saved a ton of money doing it in my garage.

Yes, that's the biggest thing that you just pointed out. When we do the work ourselves we know that it is done RIGHT!

Do they make the jeep faster? Trail better?

I guess I am a cheap ass.
No! But they do make it look better, more unique and stop better. Not a mod for everyone that's for sure!

I forget the exact distance...but the SRT w/brembos stops in a much shorter distance than the wk. I have the complete brembo conversion and the difference is VERY apparent.

nice dude! Im sure it looks good, in color of course haha. Do the fronts, then you will REALLY notice a difference if you haven't already. Red calipers always look good imo, contrast is nice :) Glad to see you save some pennies and did it yourself too, def a good feeling knowing you did it on your own, +1

The actual work for the rear Brembos wasn't that hard. I had to remove the old calipers, rotors, hub bearings and backing plates and replace them with SRT ones, except the hub bearings which can be re-used. You will also need the Brembo brake hoses and a set of pads. Then bleed the system by doing the entire job on the rear passenger side first, then move over to the rear driver's side. The Brembos have two bleeding screws so you bleed the inside one first. I paid $300 a piece for the calipers which included the brake hoses. As they are 09 bright red ones they were in excellent condition. The backing plates were $200 a piece and the rotors were $150 for the two. This cost can however come down considerably if you are able to get a couple backing plates off a salvaged SRT instead of having to buy new ones like I did. The backing plates are different between the WKs and the SRTs and have to be swapped for this mod. I would not go used for rotors or pads so, add the cost of new brake pads into this; prices for these vary. It really looks cool and they do stand out!

Very nice. Love to see some pictures. I recently ordered Power Stop slotted rotor with Ceramic pads because I wanted to keep the 18" wheels. The make a red caliper cover in aluminum as well as in matte black but I'm thinking of just painting the Jeep calipers front side using a sturdy chimney black. That way heat won't be an issue. I looked at may wheels that were SRT reproductions, but upgrading to the bigger wheel meant a lot more expensive rubber and a bumpier ride with less snow and ice capability from an all season tire. I think finding the brembo brakes from a salvage yard was a great idea. I bought new 2015 wheels with factory Michelins for $670 shipped of eBay. The price for tires alone pushed $1200 with installation. I had some 20" rims with Goodyear rubber picked out for $1500, but was lucky to find the deal I did. Brembo said are big and heavy but if I had a V-8 in this Jeep I wouldn't hesitate buying them. I just have the V6 as I don't tie anything or put loads of mileage on them.
