Question about 1983 Chevrolet Monte Carlo

1 Answer

Disc brake spring

I have brand new disc brake kit from Heidt Mustang front end kits for street rods. They use GM calipers, single piston 1978 to 1984 style. No instructions were sent on assembly. There is one small spring in this setup that I have no idea which way it installs on the pads. So far no luck finding and diagrams that show this spring and its proper intallation. Any suggestions.

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.

Changing rear brake pads


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. First you must verify yours front brake disc diameter: 280 mm or 288 mm. (On my car y have 288 mm). After that you can 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!!!

Please rate my response. Thanks!

How to retract Malibu rear disc brake cylindar

2008 grand caravan rear brakes


Older vehicles with caliper parking brakes rotated their pistons in a ratchet effect.To retract those they needed to be pushed in and rotated at the same time.I cannot stand rear disc brakes.Seems they fail way too often.GM had that issue with its W body cars (1987-up),pads would wear to steel in 6 months or less. Did the face of the piston have 2 or 4 square/rectangular/round holes in it? There is a tool to hook onto a ratchet to let you turn and push the piston back in. If you banged it in, the system may not work correctly.
Go and rent the Caliper Brake Kit from Auto Zone, it make your brake job way easier. This tool compresses the piston while it rotates clockwise. So if you are going to do your own rear brake job get this tool or something similar. 
Good luck and hope this helps. Keep me posted, Recap: The cylinder does not compress on the rears, it screws back in. A special tool for rear calipers works best but a pair of needle nose pliers will do in a pinch.

Help-Ford E-350 Brake problem


First, if the recall applies to your van, it can be done anytime. There is no time limit on recalls. Call your dealer with your 17 Digit VIN number and they can check. Please rate as solved if this is what you need. thanks.

Here is the recall:

Safety Recall 92S44 - Certain 1988-1991 F250/350 Trucks for Loss of Front Brake Effectiveness
Affected Vehicles
Certain 1988-1991 F250/350 trucks over 8500 lb GVW with 7.5L EFI or 7.3L diesel (4x2 and 4x4) and 5.8L EFI (4x4 only). Trucks under 8500 lb GVW. 5.8L EFI (4x2) and F-Super Duty light trucks are not involved in this recall. Specific vehicle information is as follows:

AFFECTED VEHICLES ASSEMBLY PLANT PRODUCTION DATES F250/350 Norfolk Job#1 1988 to 4/18/91 Kansas City Job#1 1988 to 4/25/91 Ont. Truck Job#1 1988 to 5/1/91 Mich. Truck Job#1 1988 to 5/11/91 Twin Cities Job#1 1988 to 5/29/91
Reasons For Recall
In certain extremely severe driving conditions, the vehicle may experience a loss of front brake effectiveness due to overheating of brake fluid. These vehicles have a split brake system and the rear brakes remain operational. This condition has been reported primarily in vehicles operated in mountainous regions, and on vehicles that have been in service for a minimum of one to two years and where the brake fluid has absorbed moisture from the air, lowering its boiling point. It usually involves heavily loaded vehicles driving on long, steep grades, or when towing at, or near, the Maximum Gross Combination Weight Rating (GCWR) for towing. Warm weather also appears to contribute to this condition. To correct this condition, dealers will install insulators in the front brake caliper pistons on all the affected trucks. 7.5L EFI engine equipped trucks will also have insulation installed on selected portions of the front brake lines.
-----------------------------------------------------------------------------------------
PART NUMBER DESCRIPTION CLASS DEALER PRICE F2TZ-2C361-A Kit-Brake Caliper Piston Insulator (All Except 7.5L Engines) BG F2TZ-2C361-B Kit-Brake Tube Insulator Jacket (Required Only For Vehicles Equipped With 7.5L EFI Engines) Kit Also Includes Brake Caliper Piston Insulators

Brake Caliper Piston Insulator Kit
Installation Instructions
  1. Remove the front wheel and tire assemblies.
  2. Remove the brake calipers from the rotors. Refer to the appropriate shop manual for the procedures.
  3. Remove the inner and outer brake linings.
  4. Inspect the brake caliper pistons. If the pistons are phenolic, (brown in color) no modifications are required. Reassemble the calipers as described in the shop manual. If the truck is equipped with a 7.5L EFI engine, install the brake tube insulator kit. If the truck is not equipped with an 7.5L EFI engine, install the wheels and tires and release the truck.
    If the pistons are aluminum, continue as described below.
  5. Remove the steel retainer and Nomex thermal washers from the kit.
  6. Place a steel retainer on a bench with the tabs facing up. Refer to Figure 1.
  7. Place a Nomex thermal washer over the tabs so that it rests on the barb of each tab. Then, carefully press it over the barb of one of the tabs. Repeat the procedure for each of the remaining tabs.

    • NOTE:
      Do not bend the tabs. The inner edge of the washer may crease slightly as it passes over the barb. This is permissible provided that the crease can be smoothed out once the washer is in place. The washer must be installed without tearing.

  8. Push the washer down onto the back face of the retainer. Be sure it is seated uniformly on the retainer. Once installed, do not use an adhesive or other aid to hold it in place. This is neither necessary nor permissible.
  9. Snap an assembled insulator into the inside diameter of each caliper piston. Be sure the assembly is firmly seated on the rim of the piston. See Figure 2.
  10. Install the inner and outer brake linings.
  11. Clean the caliper slide surfaces on the caliper and the spindle with a wire brush and lubricate with Disc Brake Caliper Slide Grease, D7AZ-19590-A (ESA-M1C172-A) or equivalent.
  12. Reinstall the brake calipers. Refer to the appropriate shop manual for the procedures.
  13. Install the wheel and tire assemblies.

Daewoo front brakes


The single-piston floating-caliper disc brake is self-centering and self-adjusting. The caliper is able to slide from side to side so it will move to the center each time the brakes are applied. Also, since there is no spring to pull the pads away from the disc, the pads always stay in light contact with the rotor (the rubber piston seal and any wobble in the rotor may actually pull the pads a small distance away from the rotor). This is important because the pistons in the brakes are much larger in diameter than the ones in the master cylinder. If the brake pistons retracted into their cylinders, it might take several applications of the brake pedal to pump enough fluid into the brake cylinder to engage the brake pads
