Car maintenance 101
Squeaky brakes send the same shivers down your back when someone hears a plate scratched with a knife or listens to nails on a blackboard . However, you do not have to fear for your eardrum (or for your mind) for every braking maneuver. If you are a skilled do-it-yourselfer, you can eliminate the high noise you have when you press the brake pedal in just a few hours with only basic tools. This is how.
Why the whining?
Before we discuss some of the causes and solutions for your brake headache, it is worth noting that brakes sometimes make a noise. Intermittent beeps are normal, especially if you live in a harsher climate. If you still have a brake pedal feel and can scrub the speed as normal, you don't have to worry about anything.
Simply put, brake noise is vibration. The sound is mainly due to the interaction between a brake disc, a caliper and a brake pad. Affected systems make a noise when pressure is applied from the caliper to the disc. You can pedal on the brake pedal or wear more / less speed in every brake maneuver, but your brakes may still cry because of the contact between your pad and the disc.
If you notice that your brakes sometimes only make noise, this may be due to moisture-transformed rust on the surface of a disk or pad. This can happen as quickly as & # 39; overnight, and there may be some beeping until all the rust on the components has been scrubbed.
Those who love track days with racing blocks have to get used to some squeaking. The material used to make brake pads of performance is more resistant to heat and creates greater friction, thereby increasing the resonance frequency in the audible range. For this reason, many weekend racers opt for a pad compound that is not aggressive enough to make noise or exchange pads for commuting on weekdays.
In these two cases there is no reason for an alarm, but if you start to hear a shrill metallic sound instead of a consistent, high-pitched sound, you must brake immediately. In this case you have probably worn your pads to the metal and you are delaying your vehicle without a composite buffer.
What tools and products you need
Before diving into a step-by-step guide for quieter brakes, here are some of the most important tools and products you need, depending on the solution you prefer:
- form of hand protection (we recommend a pair of mechanical gloves with a built-in grip)
- Jacks and jack stands (harbor freight has great deals all year round)
- Lug wrench
- Socket wrench (with several socket wrenches for your vehicle)
- Teflon shim
- Brake fat or anti-jamming
- Anaerobic glue
How to dampen that sound
Not every car's brake system beeps, but those who do can Usually with a DIY there can be solved in a few hours. First you have to decide whether you want to mute the sound or change the components to completely stop the sound.
The first and simplest solution is to change your pads. Depending on the connection you choose, new pads in all four corners may be a little expensive ($ 1
If you do not want to change pads, another option is to place a Teflon filler plate between the pad and the caliper piston. This does not work for every braking system – some are designed without any margin for a disc that fits without dragging the path onto the disc. You could wear your brake pad to the point where it no longer drags the shim, but that would be a waste of money. Another, more temporary solution would be to lubricate the brake pad with brake grease or to get stuck to buffer the vibration frequency.
The last, and perhaps the best adjustment (according to Popular Mechanics) is to move the support plate from the pad to the caliper piston or housing. This increases the mass of the piston and changes the vibration frequency to a point where it does not squeak. You will need the right glue for the sheet to stick for longer than a few days, weeks or months. Popular Mechanics suggests an anaerobic glue that is applied as a film or goo. When you press the plate firmly against the piston / housing, the glue sticks like a vice and is resistant to corrosion by dirt and water.
If the sound does not go away, check whether or not your car has an open recall regarding brake-related problems. You can find this information online or by calling your nearest dealer.
