Quick front rotor and brake repair cost estimate. Sign In

1997 Mits Eclipse (Base) 2.0DOHC 180k miles

So after going over 60mph...when i go to stop my car starts shaking really bad for a little. A guy i met recently told me it was the rotors. He said he would do both front rotors and brakes for 120$ if i bought the parts. I called a mechanic shop and they said they would do it for only 70$.. is that price correct? It seems fishy to me...

The $70 figure is more realistic if you're supplying the parts.

Must be a Just Brakes quote..


Wait till they find out that not only the front rotors are warped, but you have loose tie rod ends, the calipers and hoses need replacement, and the rears are needing work. I wish I had the ability to lay my hands on the hood of a car and go, "Yep, it needs rotors."

lol is there anyway i can fix the rotors and brakes now and then IF i have loose tie rods ends and calipers etc.. needs fixing can i do it later? the rears are still ok i had a mechanic check those, but then again idk.

That depends on your tools and how confident you are with a mechanical repair. Brakes seem easy and any idiot can screw them up. Its the details that make it right. We can walk you through the steps, but if you are at all worried about doing a perfect job let the pros take this. Brakes are the easiest job to screw up and cause a deadly situation.

true, well actually i shouldn't have said I, i meant to have said they lol.. right now im sure i wouldn't be able to afford all those repairs if they were messed up, but i am def going to let a pro handle it. Only thing i know how to do is change the oil lol.

REMOVAL & INSTALLATION


See Figures 1 through 15
  1. Disconnect the negative battery cable.
  2. Remove some of the brake fluid from the master cylinder reservoir. The reservoir should be no more than 1 / 2 full. When the pistons are depressed into the calipers, excess fluid will flow up into the reservoir.
  3. Raise the vehicle and support safely.
  4. Remove the appropriate tire and wheel assemblies. For rear disc brakes, loosen the parking brake cable adjustment from inside the vehicle.
  5. Remove the caliper lock and guide pins and lift the caliper assembly from the caliper support. Tie the caliper out of the way using wire. Do not allow the caliper to hang by the brake line.




Fig. Fig. 1: Location of the front caliper guide pin (bottom) and lock pin (top)


Fig. Fig. 2: Use a suitable wrench to loosen the caliper mounting bolts


Fig. Fig. 3: Withdraw the caliper guide pin from the assembly
  1. Remove the outer shim, brake pads and spring clips from the caliper support. Take note of positioning of each to aid in installation.




Fig. Fig. 4: View of the brake pad assemblies with the caliper lifted from the support


Fig. Fig. 5: With the caliper lifted up away from the support and remove the outer pad ...


Fig. Fig. 6: ... then remove the inner pad from the assembly


Fig. Fig. 7: Remove the upper clip (see arrow) and inspect it for damage ...


Fig. Fig. 8: ... there is also a bottom clip which should be removed, inspected and replaced if necessary


Fig. Fig. 9: Exploded view of the front disc brake pads and related components-1990-94 vehicles


Fig. Fig. 10: Removing rear disc brake pads, shims and spring clips from the caliper assembly
  1. Install the wheel lug nuts onto the studs and tighten. This is done to hold the disc on the hub.
  2. Using a spring scale, turn the disc in a forward direction and measure the rotation sliding resistance of the hub.




Fig. Fig. 11: Use a spring scale to measure the hub turning torque-front shown, rear similar
  1. Clean the caliper piston. For front disc brakes, use a C-clamp or equivalent tool to press the piston back into the caliper bore. For rear disc brakes, use driver tool MB990652 or equivalent, to thread the piston into the caliper bore. Be sure at this point, that the stopper groove of the piston correctly fits into the projection on the replacement brake pads rear surface.




Fig. Fig. 12: On front disc brakes you can use a suitable clamp to press the piston into the caliper


Fig. Fig. 13: For rear disc brakes, a driver tool to install the piston into the caliper


Fig. Fig. 14: Use the driver tool to thread the piston into the rear caliper bore To install:
  1. Install the brake pads, shims and spring clip to the caliper support. Install the caliper over the brake pads.


Be careful that the piston boot does not become caught when lowering the caliper onto the support. Do not twist the brake hose during caliper installation.
  1. Lubricate and install the caliper guide and lock pins in their original positions. For front disc brakes, tighten guide and locking pins to 23 ft. lbs. (32 Nm) on vehicles built up to May, 1989. On vehicles built during and after May, 1989 to 1990 vehicles, tighten caliper guide and locking pins to 58-72 ft. lbs. (80-80 Nm). For 1995-98 vehicles tighten the front caliper guide and locking pines to 65 ft. lbs. (88 Nm). For rear disc brakes, tighten the caliper guide and lock pins to 36-43 ft. lbs. (50-60 Nm).
  2. For rear disc brakes, start the engine and forcefully depress the brake pedal 5-6 times. Apply the parking brake, then make sure the adjustment is within specifications. Adjust the parking brake cable, as required.
  3. Check the disc brake drag force as follows:
    1. Start the engine and press the brake pedal firmly a few times to seat the pads.
    2. Once the pads are seated, shut the engine OFF.
    3. Turn the brake disc forward 10 times.
    4. Using a spring scale, measure the rotation sliding resistance of the hub in the forward direction.
    5. Calculate the drag torque of the disc brake by subtracting the value obtained in Step 8 (force required to turn hub alone) from the value obtained in Step D (force required to turn hub with caliper and pads installed). Compare calculated force with desired force of 15 lbs. (70 N) or less.





Fig. Fig. 15: Measuring brake drag force
  1. If the calculated disc brake drag force is greater than specifications, disassemble and clean the piston. Check for corrosion or worn piston seal and check the sliding condition of the lock pin and guide pin.
  2. Install the tire and wheel assemblies. Connect the negative battery cable.
  3. Lower the vehicle. Test the brakes for proper operation.


INSPECTION


See Figures 16, 17 and 18
The disc brake pads have wear indicators that contact the brake disc when the brake pad thickness becomes 0.08 in. (2.0mm) and emit a squealing sound to worn the driver.
Inspect the thickness of the brake linings by looking through the brake caliper body check port. The standard value of the brake pad is 0.39 in. (10mm). The thickness limit of the lining is 0.08 in. (2.0mm).
When the limit is exceeded, replace the pads on both sides of the brake disc and also the brake pads on the wheel on the opposite side of the vehicle. Do not replace 1 pad on a caliper because the wear indicator is hitting, without replacing the other pad on the same wheel as well as the brake pads on the other front or rear wheel, as applicable.
If there is a significant difference in the thickness of the pads on the left and right sides, check the sliding condition of the piston, lock pin sleeve and guide pin sleeve.


Fig. Fig. 16: Inspect front disc pad thickness through caliper body check port


Fig. Fig. 17: The disc brake pads have wear indicators which will make a squeaking noise when the pads become worn and need to be replaced

You're just getting off on a tangent that you don't need to. DS was trying to be a smart ass by indicating that he already knew (but obviously didn't) who gave you the estimate and that they were dishonest and would be telling you about a dozen other things you will need (but probably don't). Just go with your original plan and see what they say.

I apologize to the OP for that. I guess some of HT is rubbing off on me.
