Question about 1995 Saab 900

1 Answer

Rear brakes Hi......... I have a SAAB 900s. I have serviced all the brakes calipers by stripping them done and cleaning the inside. When I bleed the brakes, fluid can seen coming out of the brakes. However, when driving the car, the brakes do not work. I can tell by the stain mark left on the rotor and the temperature is about 60 to 70 degrees C. ( I used a temperature gun to measure the temperature)

You need to unscrew the caliper piston out until you can just get the caliper nto the disk or it will take weeks to self adjust.
hope this helps

I have replaced 3 disc brake calipers on my 2001 pt cruiser. after bleeding all 4 brakes 3 times, I started the car and brake pedal goes to floor. is my brake booster shot?


Michael:

You must start bleeding the brakes at the wheel farthest from the master cylinder (usually the right rear), then the next farthest from the master cylinder, then the next, then the closest. If your master cylinder is at the left front of the car, start with the right rear, then the left rear, then the right front, then the left front. If you don't bleed the brakes in the correct order, you are just shifting the air in the lines from one line to another. Make sure that you close the bleeder before letting the brake pedal up, and the engine should not be running when you bleed the brakes... Make sure that the emergency brake is off. Make sure that the master cylinder does not run out of brake fluid at any time that you are bleeding the brakes.

My 1997 saab 900s brakes need to be pumped sometimes in order to get the car to stop any suggestions?


You need to bleed the air out of the 4 brake lines.

Bleed valves are attached to the caliper housings at each wheel - 10mm wrench should do it!

Be sure to attach clear tubing to the bleed valves and put other end into a clear container with some brake fluid already in it. this is so the brake lines don't suck air back before you close off the valves.

Close the valves when no more air bubbles come out.

You will need someone else pumping the brakes for you.

Before you start, open brake master cylinder and have a can of new brake fluid handy to refill reservoir as you go.

Start with wheel farthest from the master cylinder and work forward.

Need to know how to change brakes rotors and calibers on 1996 gmc jimmy


Hi Friend:

#1) Break Loose your Lug Nuts,Just A Little don't Take-them off yet.

#2) Jack Front end off the Ground,Support with Good jack stands,Keep Truck in Park and Emergency brake Applied.

#3) Now Take off your Front Wheels-Tires.

#4) Now on the Inside of your brake rotor on each side,there are 2-Caliper mounting bolts. Allen Bolts 3/8" Allen Socket or Allen Wrench.Break the 2-Bolts loose and Remove them.

#5) Now after the Caliper Bolts are removed ,Loosen the Brake Line going to the Calipers using a Flare wrench.You'll need to have a Drain Pan handy to Catch the Brake Fluid.

#6) Now you'll need a C Clamp ,to compress the caliper piston back in the Caliper. NOTE: before you compress the Caliper pistons ,take off the master cylinder cover and using a suction bulb remove about 1/2 of the fluid from the Front Resevoir.the larger of the two.

#7) Now placing the C-Clamp over the Caliper housing turn it clockwise to compress the Piston all the way in.

#8) now you can remove your caliper and the pads,same for Both Sides. AND remove your Rotors they are held on by the Calipers and your Lug-Nuts.It Should come right off ,if its a little rusted and Stubborn take a Plastic Headed Hammer and Tap it all around the Old Rotor.Until it comes off.

#9) Now Slide your new Rotors on the HUB and over the lug nuts.

#10) Get your new caliper Making sure you have the Correct Caliper its Marked Left or Right Sides. It will only work on the Side its made for.

#11) Now put your Anti Rattel Clips on the Correct Sides(Inside) that fit into the New Caiper Piston.also use some brake lube on the back on the new brake pads where they touch the caiper housing.

#12) With both pads in the Caliper Slide the Caliper over your New Rotor. This is for both sides.

#13) Put your brake line back on using the new brass washers that came with your rotors/or Caipers.

#14) Now Put your Caliper Mounting bolts in and tighten up to 38 Foot Lbs.

#15) When you have both sides done Fill up your master Cylinder about a 1/4 " from top.

16) Now you'll need to bleed them ,Get a Friend and have them Slowly push the brake pedal down,after he says its down you open the bleeder valve until fluid and air come out==Now tighten it back before your friend raises his foot up off the pedal.During bleeding keep checking your Master Cylinder to keep it full of fluid.

#17) Start your bleeding from the Right Rear to Left Rear to Right Front and Last Left Front. Always bleed from the farthest brake or Wheel from the Master Cylinder and work your way to the Master.

#18) After you have No air coming out of the bleeder valve and you do have good clean brake fluid.Your Done Bleeding;You should have a Good tight and High Brake Pedal. NOTE: you DON't start the Truck to bleed the brakes.

#19) Now just Put your Tires back on and Tighten your Lug Nuts and you should have good Brakes.

I'm sure that this will get you good brakes and on the Road Again.

Replace rear brake pads


Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
rear_brake_pads.jpg Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
rear_brake_pads_2.jpg To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
rear_brake_pads_3.jpg After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
rear_brake_pads_4.jpg With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
rear_brake_rotor.jpg Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
rear_brake_rotor_2.jpg Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
rear_brakes_7.jpg Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
rear_brake_rotor_3.jpg After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
rear_brake_rotor_4.jpg Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

Bleeding brake system how?


BLEED BRAKE SYSTEM

Make sure one end of the Jeep is raised (starting with the rear end) and secure on jack stands and the wheels on each side have been removed. If you have been working on the brakes, this should already be done.

Connect a clear rubber tube to the bleeder valve on the right rear brake caliper. Start with this end and side because it is farthest from the master cylinder.Place the tube's other end into a container partially filled with brake fluid.

Open the bleeder valve on the caliper and have an assistant press on the brake pedal inside the Jeep. Look for a mixture of air and fluid to come out of the valve. Once all the air is purged and the fluid runs cleanly from the valve, close the screw and remove the tube.

Repeat the process for all four brakes. Move to the left rear next, followed by the right front and the left front. If you need to, reconnect the Jeep's rear wheels and lower the rear end before raising the front end and removing those wheels.

Check the level of fluid in the master cylinder periodically as you bleed the brakes. If the level drops below the needed fill line, add more fluid. Use fresh fluid, not any that you have bled from the brakes.

Start the Jeep's engine after bleeding all the brakes and press on the brake pedal. You might need to do this repeatedly to seat new brake pads you just installed. Turn off the engine and hold down on the pedal. Bleed the brakes again if the pedal sink within 15 to 20 seconds.

1990 SAAB 900S REAR BRAKE CALIPERS


Sorry, gentlemen; NO 'C' clamps should be used on the rear callipers of 1988 to 1993 and 1994 convertible SAABs! Unless you want to replace the callipers, that is...

There is a calliper adjusting screw, at the rear of the calliper, hidden behind the parking cable. Unhook and remove the parking cable from the back of the calliper. You'll see a hex head located on the back of the calliper, between the hook to attach the end of the parking cable, and the hole through the bracket where the cable passes to the front of the car. The hex head is most easily seen if you hoist the car; it's not the most obvious until you've found at it a couple of times, then you can do it by touch with the car on a jack stand and without getting underneath!

Remove the hex head bolt, about a 12 mm or so wrench/socket, and you can then get at the calliper adjusting screw to tighten or release it as appropriate; the adjusting screw has an internal hex head socket, use a 4 mm Allen key. Likely the adjusting screw will be a bit stiff; spray into the hole with penetrating spray and let stand a few minutes before trying the Allen key.

Good luck!
