Question about 1983 Cadillac Eldorado

2 Answers

Have installed new (rebuilt) calipers on '83 El Dorado. Parking brake doesn't work on passenger side. Had to use tool to press piston in far enough for installation on other side (driver) but this side had piston depressed enough to install without use of tool. Driver's works, passenger side does not. It is supposed to self adjusting but how long does that take? Do these need to be set up in some manner ( which I might have done unknowingly in depressing the other side ) ? Also if piston rotates as it adjusts why would they make a brake pad with a clip for an anti-rattle spring that can engage the piston and stop it from rotating?

Your description gives me a suspicion the calipers weren't rebuilt to a very high standard.

The pistons don't turn as they are pushed out but mostly they have to be rotated or screwed and pressed in prior to fitting the pads.

Once fitted and bled ensure the caliper parking brake lever is hard against the backstop and then press the brake pedal hard a few times and the adjustment should be complete after removing any slack or free play from the parking brake cable.
With a new or quality rebuilt caliper a good parking brake should be obtained without needing to shorten the cable so the caliper levers are lifted from the backstops. That is the sort of compromise needed as the internal components become worn.

Once calipers are installed go to pump break pedal 4or5 times hard to move pistons firmly back in place.

SOURCE: On a 1999 cadillac deville I replaced the front

Try disconnecting the battery fo at least 60 seconds, this will manually re-set the computer. It will sometimes take a day or so for the light to go out. If it has ABS find a dead end street and get up to 40-45 MPH and slam on the brakes and check that everything is ok. That's the only way to properly check and not endanger any people. Good luck.

SOURCE: replace window switch for 1997 el dorado

I have the same problem. I just replaced the switch ($60 from the Internet) Easy replacement, but the problem persists, Here is my next plan of attack... The PCM (vehicle computer controls the power windows for your vehicle. check the power window relay under the hood before repairing PCM. Also the cheapest way is to call local garage and ask if they have a TECH2 scanner to talk to the PCM. The Dealer will charge you about $95hr. to do this.

SOURCE: I changed the shoes on

The first time you use the brakes on a drum the shoes will equalize with each other. This may be the reason it doesn't seem adjusted right. Readjust the shoe adjusters till you can just hear the scrape and try again.

How can i compress the caliper piston back of audi a6 2000 2.8l awd what kind of tools i need . Vise grip is not working.


For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also.
But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!!

For front brake pads. You should buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow:
1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose!
2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper.
3. Now you must thoroughly clean the brake calipers (free of grease).
4. Remove outer brake pad from brake carrier.
5. Pull inner brake pad out of brake caliper piston.
6. Check up the brake fluid level on the reservor, and emptying if neccessary!
7. Push piston back into brake caliper housing.
8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward).
9. Install outer brake pad into brake carrier.
10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm.
11. Install both caps.
12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!!

Check brake fluid level and top up if neccessary!!!

How do you get the rear caliper to retract when installing new brake pads? On a Lincoln 2007 mkz?


Need to buy a tool at auto parts store ,that
fits the rear caliper piston,so you can turn it
clockwise. ( Looks like a cube) $8.00

What your doing is actually turning in or back -- the
parking brake adjuster.

The tool will be turned with a 3/8" extension & ratchet

Opening the bleeder valve will help as you have to
push the piston in as well as turn it in.

Need to bleed all 4 wheels every 2 years anyway.

You may have to file the tool to get a combination
that will work
I had to do that with the Lincoln LS

Once the pads are on,you ratchet up the parking
brake,bringing the pads in contact with the rotors.

Press the brake pedal a few times before going into
rev or drive, to seat pads

The notch on the caliper piston, goes to the top
so the pin on pads will fit

Just completed new back pads. Screwed in rear pistons with the tool and adjusted the parking brake. went for a test ride and rear passenger rim and rotor hot and smoking?


you may have to pull that side off and see if the caliper piston moves back in place freely,if not then you will have to replace that caliper and bleed the system.some times when you move the piston back when installing new brakes the piston seal rolls and causes the piston to stick/seize when the pedal is applied.

Have taken apart but cant get new or old pads back on now. not enough space and part that should move back to make space wont seems to be jammed or siezed. have tried letting out brake fluid but didnt...


  • To install: Front
  1. Compress the piston of the disc brake caliper.
  2. Install the brake pads and caliper assembly.
  3. Lubricate the guide pin. Tighten the guide pin to 16-23 ft. lbs. (22-31 Nm).
8267164.gif

REAR :
  1. Pull out the pad springs and then remove the pads and shims.

To install:

  1. Clean the piston end of the caliper body and the area around the pin holes. Be careful not to get oil on the rotor.
  2. Carefully turn the piston clockwise back into the caliper body (this can be done with a pair of needle nose pliers). Take care not to damage the piston boot.
  3. Coat the pad contact area on the mounting support with a silicone based grease.
A special tool is available to rotate the caliper piston

WARNING

Do not press the piston into the bore as performed on the front disc brakes. Due to the parking brake mechanism, the caliper piston must be turned into the bore.

Compressing the rear disc brake caliper on 2008 grand caravan


The rear calipers on these models require a special tool that compresses and turns the piston in at the same time -- most parts stores carry this tool.

It is called a caliper piston press -- and it installs where the pads would go and acts like a c-clamp,when turning handle it will turn the caliper piston backinto the caliper as it compresses it.
Anytime the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the Parking Brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor,MILLER Special Tool 8807, . Any other seating method will damage the self-adjuster mechanism.
Good luck and hope this helps.

CANT GET THE PISTON TO RETRACT ON THE CALIPER


With rear brakes the caliper piston must screwed in. It usually has a parking brake mechanism that has to screw out as the pad wears down. When you install a new fat pad, the piston won't retract with normal pressure of a clamp but must be screwed back in on the parking brake screw. This can be done with a long nose pliers but tools are made just for the purpose. I hope this helps.
