    The power booster is not the problem. Sorry.

    Are you getting fluid to the calipers and the wheel cylinders?

97 saturn brake problems. Replaced master cylinder, both front calipers and rotors. Replaced both rear wheel cilinders shoes and drums. Also replaced all rubber brake lines yet no pedal after bleeding....


Get another master cylinder,If you want to really find out if the master cylinder is goo open one of the lines have someone pump the brake,with your finger over the open cylinder line you will have pressure coming out, and if you feel vacuum has your assistant releases the pedal that a sure sign the master cylinder is not working,Also when you have a master cylinder before you install you need to bench bleed it

1999 Yamaha Kodiak Front Disc Brake - Rebuilt master cylinder with new parts. Replaced orings on piston in front caliper and bleed brakes using new fluid. The piston will not retract. What is proble


The brake hose is clogged. When under pressure from applying breaks, the piston is forced tight to the rotor. When released the fluid will not return through the hose because there is no real pressure. Replace the hose.

I changed about everything,cylinders calipers,shoes,pads,and new rotors. then after following correct bleeding proceedures still no pedal.oh, and no e- brake either .what the heck am i doing wrong?(1991...


If you have no e brake that tells me your problem is something to do w/rear brakes. Pull your re brakes back apart and make sure everything is seated properly. Sounds like you didn't adjust rear shoes out far enough. Double check rear adjustment THEN bleed again - rt rear -> lft rear ->rt frt -> lft frt.

How can I change the rotors and brakes on a 2006 Cadillac?


Front brake
Step 1: Identify Front Disc Brake Components
brake_pads_rotor.jpg
Front Wheel Drive Brake Assembly
Most front disc brake components include: brake rotor, brake pads, brake caliper, caliper mount and brake flex hose. Brake service usual occurs between 20,000 and 40,000 miles depending on driver habits, road conditions and brake pad/ rotor materials used.
Step 2: Remove Brake Caliper to Replace Pads
brake_pad_set.jpg
Removing Brake Caliper Mounting Bolts
Locate primary caliper mounting bolts; apply wrench pressure counter-clockwise (When looking at the head of the bolt) to remove the bolts, upper and lower. Make sure the bolt threads are in good shape and replace if necessary.
Step 3: Remove Front Brake Caliper
remove_brake_caliper.jpg
Remove Front Brake Caliper
After removing the primary caliper mounting bolts lift the brake caliper off of the rotor and then tie or secure to the side, being careful not to bend or kink the brake caliper flex hose. Thoroughly inspect brake caliper and brake hoses for leakage, cracks or chaffing and replace as needed. Next remove the brake pads (If not mounted in the caliper) and secondary caliper mounting bolts. Notice how great protective gloves work, most technicians use them on the job today.
Step 4: Remove Brake Pads

Remove Front Brake Pads
Once the brake pads have been removed, make sure if there is anti rattle hardware to transfer to the new brake pads. Some brake pad manufacturers will include the proper lube (Caliper slides) and anti-rattle hardware to ensure proper performance of their product.
Step 5: Remove Caliper Mount
remove_brake_pads_holder.jpg
Remove Caliper Mount Bracket
Finish removing secondary caliper mount bolts and remove caliper mount. Note: clean and lube caliper slides and pad friction surfaces of all foreign material or build-up.
Step 6: Remove Brake Rotor
brake_rotor.jpg
Remove Brake Rotor
With the caliper mount out of the way you can now remove the brake rotor. Sometimes it can get stuck so you may need to tap it with a hammer or use penetrating oil to free it up. Some manufacturers use small screws to hold the rotor on as well. Clean and inspect wheel studs, replace if any are damaged. Also clean bearing hub rotor mount surface to ensure the proper mounting of the new brake rotor. Inspect the ABS sensor wheel for cracks or damage and replace as needed.
Step 7: Depressing the Brake Caliper
compress_caliper.jpg
Resetting Brake Caliper
To install the new brake pads you must retract the brake caliper piston. Remove the master cylinder lid or open the brake caliper bleeder screw to allow excess brake fluid to be released if necessary. Install C clamp tool and gently tighten clamp until caliper piston is fully depressed. Note: use old brake pad to protect the caliper piston. Close the bleeders once the piston is retracted completely
Step 8: Installing New Brake Rotor
new_brake_rotor.jpg
Install Brake Rotor
Install new brake rotor, the new rotor is manufactured with a protective film over the rotor to keep it from rusting, remove protective film with brake cleaner before installing; also after the brake job is complete you may experience a small amount of smoke from the rotor when first used. This is normal and will go away after the first couple of uses.
Step 9: Installing New Front Brake Pads
new_brake_pads.jpg
Installing New Brake Pads
Reinstall the front brake caliper mount, and then install front brake pads. Make sure the pads are seated properly in the caliper mount; it must be a close fit to work properly..
Step 10: Reinstall Front Brake Caliper
front_brake_rotor_pads.jpg
Re-Install front Bake Caliper
Reinstall front brake caliper and reinstall caliper-mounting bolts, recheck all mounts and mounting bolts. Check the caliper slides to be sure there is no bind and that the caliper moves freely back and forth on the caliper slides. Bleed brake system per manufacturer's specifications to relieve any air trapped in the system. Before driving the vehicle, push the brake pedal down and let it up slowly, repeat until normal brake pedal operation resumes, this operation is forcing the brake pads to travel to the brake rotors.

New rotors and calibers, with pads replaced and now every three to four days must add brake fluid and brakes work fine no sponge feeling.


Check for leaks around brake calipers or cylinders, check for leaks around brake master cylinder, may be leaking from master cylinder into brake booster, remove vacume line from booster and see if you can detect oil inside, if your adding oil to brakes every three to four days a leak should be easy to find.

I had the exact problem today on my in-laws 06 jetta. Come to find out - this model has an electrical parking brake in the rear. The piston will not go in manually like other disc brakes. You must disconnect the electrical wire in the back and run a jumper to the connection from a power source like the battery and the piston will go in.

Removal off fromt brakes and rotos on 4x4


Disc Brake Pads Removal & Installation Front To Remove:

  1. Remove the cover on the master cylinder and siphon out 2/3 of the fluid. This step prevents spilling fluid when the piston is pushed back into the caliper bore.
  2. Raise and support the vehicle safely.
  3. Remove the wheel and tire assembly.
  4. Compress the brake piston back into its bore using a C-clamp.
  5. Remove the 2 caliper mounting bolts. Lift the caliper off the rotor.
  6. Remove the inboard and outboard brake pads.
  7. Remove and discard the anti-rattle clips.
To Install:

  1. Thoroughly inspect, clean and lubricate all caliper slide points, bolts and hardware.
  2. Install new anti-rattle clips.
  3. Position the inboard and outboard pads into the support bracket
  4. With the 2 pads in position, place the caliper over the brake rotor and align the holes in the caliper with those of the mounting bracket.
    1. Install the caliper mounting bolts through the sleeves in the inboard caliper ears and into the mounting bracket.
    2. Tighten the mounting bolts to: 74 ft lb. (110 Nm) 1500 series
    • 80 ft lb. (110 Nm) 25/3500 series.
    1. Install the tire and wheel assembly. Lower the vehicle.
    2. Add fluid to the master cylinder reservoirs so they are 1/4 in. (6.35mm) from the top.
    3. Test the brake pedal by pumping it to obtain a hard pedal. Check the fluid level and add fluid as necessary.

    Replace brake hoses,they have an inner core that has ruptured and the outside rubber core is keeping pressure on the caliper with you foot off the brake. This will fix it! A common problem for this vehicle.
