    I took it to a repair shop. I don't think the hoses were replaced.

    yes, it does feel like the truck is dragging, like i'm stepping on the brake & gas at the same time.

  • queentrouble Jul 21, 2009

    I took it back to the shop. He called & said he replaced the hoses today, but the brake fluid is contaminated, he drove it around & said all 4 wheels locked up. Now he says the master cylinder might be bad. Is there a way to tell if it's bad or do I have to keep buying parts until one of them fixes the problem?

    does it feel like truck is "dragging" ? if so brakes are not releasing right. try checking farther back,like the resevoir. make sure return ports are free of dirt.

Have you ever changed Brake fluid?
1-After flushing out entire system, Flush out the newly changed calipers. throughly
2-Make sure the pistons on Calipers can move in and out easily by using brake clamp to check.
3- If you don't have pistons moved smoothly then you have bad calipers causing locked up then brake pad burning.

Hope this can help.

This sounds like a caliper hanging up and not releasing. Are you sure the calipers were replaced? I would take this back to the shop where it was done as you will quickly ruin the new pads and rotors if the calipers are not operating correctly.

Mazda5 rear right brake gets hot, sometimes smells burning.


Try simple/free things first: put car on jack stands,turn wheels to see if you hear pads/shoes dragging after brake pedal on/off,pads should free-float after brake pedal release and if not releasing (by the way,was any brake fluid spilled accidentally on the pads??),more than likely bad caliper;sure the pads are correct ones (thickness) for your car rotors/calipers???. Hope this helps. Alberto

Shakes really bad from 55 to 70 mph


First & Foremost, If Smell Of Hot Brakes, Remove One Or Both Front Tires, Use A Flash Light & Look At Both Brake Pads From The Top Side, Check For Thickness Of Pad. Remove Brake Caliper, 2-13mm Bolts, Top & Bottom, Should Slide Up & Off Of Rotor & Brake Pads, Maybe With A Little Light Prying.After Caliper Is Removed, Remember Those Two Bolts You Removed To Remove Brake Caliper, Those 2 Bolts Attached To Brake Sliders, They Should Slide In & Out Very Smoothly, If They Do Not You Will Have To Replace The Bridge (The Whole Piece Those Sliders Are Attached To, 2 Bolts On The Back Side, Will Come Right Off After Bolts Are Removed. Sometimes You Can Bring Them Back To Life By Cleaning Them Out With Carb Spray Then Compressed Air & Ceramic Silicone Grease (Purple Pack From Advanced Auto Counter) Make Sure Both Pieces Are Clean Before Placing Back Together. If They Are Stuck Inside Bridge Piece I Suggest Replace Caliper Mount Or Bridge. (Some Parts Stores Call It Different Names) When Doing A Brake Job Always Check Your Caliper Release Pins & Make Sure They Slide Easily, If The Caliper Does Not Return That Could Be The Smell Of Overheating Brake Pads & Vibration, Also, Your Caliper Will Not Return & Will Wear Top Or Bottom Side Of Pad Very Badly. Good Luck! Probably A Good Idea While You Have It Up On Jack Stands To Pull Up On Bottom Of Tire & Feel If There Is Any Play Or Movement Up & Down, Should Be No Movement, If There Is Movement Your Lower Or Upper Ball joint Could Be Excessively Worn, Should Be Replaced & Realigned.

I'm driving a 2000 Chrysler 300M. Had front brake pads & rotors changed 2 weeks ago. Front end has been noisy since & I suspect sticking calipers , as i was informed they did not get clean


The front calipers are not the problem...did a shop replace the pads and rotors? Or did a friend replace these parts. The Chrysler front pads and rotors are an excellent design...easy to service and replace parts...only 2 bolts hold on each caliper, and the rotor is held in place with the caliper, and wheel. My first thought was a front wheel bearing is grinding, but you should have noticed this before the brake parts change. The pads could be installed backwards also...my second thought was you may have a loose wheel or two...retighten all 5 lug nuts by using the "star" tightening method, you may be surprised that the loose lug nuts are the only problem. Hope this helps.

How can tell if brake caliber is sticking?


Park on level. Put transmission in neutral, emergency brake on, and block or chock a rear tire, so car won't move when you raise that front tire with a jack. Use a jackstand or big block to stabilize car (safety first!), when it's raised.
Now try to spin tire. If caliper is stuck tire will be very difficult to rotate.
Found the problem yet? Take the wheel off and investigate further. The burning smell has to come from somewhere. Any sign of brake fluid leaking?
Have somone pump the brake while you watch the caliper. You should see a very slight movement when caliper pushes pads against the brake rotor. When brake is held, the rotor should not turn. If it does, the caliper is stuck inside the bore, and will have to come off for rebuild or replacement.
Good luck.
Hope you find the problem,

Need to repace front brakes and rotors, the car only has 31000 miles on it!!


The brake pads are well within a good long life. Brake wear life depends on a number of factors, the most significant is the driver. Most people feel that they are easy on brakes and that is usually not true...

Rotors are damaged by: normal wear; waiting too long for pads and damage from metal to metal contact; and HEAT. Heat damages rotors and causes them to warp. Cars now days have less material on the rotors and therefore they have shorter life.

On some vehicles it is only slightly more to replace rotors, versus resurfacing them. A resurfaced rotor has less material, so warping happens faster.....Some shops just routinely replace rotors, rather than resurface for just this reason.

Other shops routinely replace calipers, which can be agrued either way, but a caliper that hangs slightly will cause rotor warp. My preference is to replace calipers when they need it, by leaking or binding....

My 1991 Lincoln town car sat for awhile. Now when driving smell a burning electrical smell and when braking it pulls to the left. Any idea what the problem is?


You have a lot of rust on all your brake components

You will need to completely strip all 4 brakes & remove
all rust and lube necessary parts

Don't misunderstand my point here

You do not necessarily need new rotors or brake pads

You may want to however, replace the flexible rubber
brake hoses, as they may have collapsed inside and
your brakes do not release,thus the brake pad smell

Also you could have rusted and frozen caliper pistons

The rust,the flex hoses & possibly the calipers, are your
problems,and the cause of the bakes not releasing

After driving for around 30 minutes, the brake


That sounds like the "Porportioning valve" is defective.
You may want to go to your local library and check out a Chilton's, or some other repair manual for the "how to" to fix yourself or take it to a tech you can trust.

2002 ford f350 deisel brakes pedal feels hard and dosnt stop verry good well driving. Brakes smell like they are burning when I stop. Just replaced front rotors,pads and calipers


You should have a hydraulic brake booster. a common failure item on fords and also would cause your symptom. the burning smell, I would go back and recheck all the brakes. Maybe a problem with the e-brakes, or an issue with the front or rear calipers. Possibly a damaged steel or high pressure brake line. Good luck.

While driving today I noticed a burning smell and when I got out the front right wheel had smoke coming from the rotor and brake assembly what sould I do


Sounds like either the brake caliper has seized up or one of the brake pads has got jammed up. You need to remove the caliper and investigate further. ICheck to make sure the piston/s in the caliper move. Also remove the brake pads , clean up the slides and apply some brake grease on the tips of the brake pad metal backs where the may contact with the caliper and mounting brackets.
