    When replacing the power brake booster, how do you get at the lower left nut inside, under the steering column.
    The steering column has a plastic cover over the universal joint that gets in the way for access to the bottom left nut.

      You need to use universal jointed sockets and wobble drive extension bars. There are no rules here. You use what ever your toolbox has that can help get around obstacles like you describe. Only person who *might* know (if he were able to remember which I doubt) would be a mechanic that presently is working in a Cadillac dealer shop. I think I speak for many mechanics out there when I say we don't usually remember the exact strategy we iuse to do certain repairs. We decide the strategy after seeing our problem and then go to our tools. Sometimes we remember enough to tell another (depends on how often we do a particular job) and often we don't. One thing that always remains, there are no rules. Use all the tools available in your tool box and in some cases you go buy a tool that you do not have. Universal joint sockets, wobble drive extensions, short stubby wrenches, crow foot wrenches, whatever it takes.

    Wheel noise mostly when breaking.
    I heard noises about 6 months ago when I would hit my brakes... woot, woot, wooot, wooooot, woooooooot. I changed my brake pads and the noise went away. The noise is back. Now I hear it again (very faint) when I am coasting or going at a low speed. The noise is ...

    My rear driver side wheel has a brake leak
    There is a puddle of brake fluid under my rear driver side wheel. When I push the brake pedal down it goes all the way to the floor. Could that leak cause my brakes to totally go out or is it a bigger issue like a master cylinder or something like that.

      Most likely have a rusted through (porous brake line) that has to be fabricated and replaced. You are now stopping on the front brakes only and that is not safe but it will stop, just allows pedal to sink down a lot.

      Several possibilities; faulty / loose / worn wheel bearing, loose brake caliper mounting, warped rear brake rotors.

      The caliper piston phenolic material is easily damaged and more prone to seizing in the piston bore than the metal ones.
      Also, they are less likely to survive one caliper rebuilding as the old crud that sticks to the pistons are harder than the phenolic piston itself, so it can't be removed from the piston without destroying the piston itself.
      The metal ones can last much longer and will not crack or fracture as the phenolic pistons will when they are removed. You can't grab them with pliers to pull them out as they will crumble, and when you use compressed air to push them out, they can easily fracture.
      Recommend to obtain replacement / remanufactured brake calipers with steel pistons - as long as the brake fluid is regularly changed to remove dirt and moisture, the pistons / calipers should not seize.

      Check the many on-line auto parts sources, such as; www.autopartswarehouse or www.rockauto.com for the replacement parts. For example, they (RockAuto) list the remanufactured brake caliper (front) with metal pistons from around $43.00 each for your vehicle. These part numbers are for the front calipers with metal pistons instead of the phenolic material; Wagner part # CR135021S / CR135020S.

      Please detail the problem that is happening in more detail. I do not just want to assume that since you mentioned "shuddering" that this automatically means that the front rotors are warped. I do not know what brake option codes you have in your DTS but I will tell you that the rotors should be replaced and not turned (ever) and that the pads that you should be installing should be AC DELCO only. Look on the RPO decal (regular production option) in the glove box. Note the brake option codes. If you see J55 (heavy duty power brakes) then the ACDELCO Part # 1710978 is for front brake pads. If you see JL9 only without J55 then the front brake pad set part # is ACDELCO Part # 1710955. If the caliper pistons move inward equally side to side (not binding as you push them in with a C-Clamp or other suitable tool, then the calipers are good. make sure the slides are not frozen.
