Front rims are warm/hot

[gomezgomez]

I noticed that both the front rims are hot/warm after a drive on this new car I brought last month (was released 2 weeks ago).

Is this expected behavior?

The front brakes are ventilated discs type. Transmission is CVT.

The temperature, if I try to describe it, is not burning hot or "nakakapaso" hot - it's like newly-made-coffee hot. You can linger your palm/fingers there for a while. Lug nuts are also hot, but the middlemost part isn't.

The temperature is a lot hotter than the back rims.

mention make and model.. honda accord?

Given the amount of friction needed to stop a car, normal na maginit yan. Mags should be warm or hotter but not nakakapaso.

Brand new ba ang "new car" mo?

it's normal.
auto books describe the heat of disk brakes as "comfortably hot".
but i agree, "comfortable" is a big range among humans.

it is because the disk brake pads are always lightly touching the brake rotor, generating heat whenever the wheel rotates, even as the brake pedal isn't being stepped on.
rear drum brake pads don't touch the drum, except when the brake pedal is stepped on. drum brakes don't normally get as hot as the disks.

to be sure, jack up the front of the car, so's the tires do not touch the ground. then rotate the wheels using your bare hand. they should rotate easily, if the brakes aren't "dragging" significantly..

I'll try this one. Salamat! Para kasing ang layo ng binyahe sa init nya haha.

Normal lang yan. Nothing to worry about.

You also posted about the groaning/ grinding sound whenever you use your brakes, right?

It could be your front brake calipers need adjusting if they're causing a lot of friction and heat.

If your car is still in it's break-in period of below 1000 kms. then I would observe it until the right time to take it to the dealer.

Brake calipers either front or rear are not adjustable.

Front wheel drive ba ang auto mo?

If it is front wheel drive then that should be the case

Energy generated by the engine is transferred to the front wheels that's why both front wheels are doing the grind

It's normal.

Disc brakes are very efficient at its job (which is to apply friction to convert kinetic energy to heat). Also, the front axle provides 60-75% of the vehicle's stopping power. It's also the reason why the front brakes are typically larger than the rear brakes and in many vehicles, the rear axles are relegated to having drum brakes as a means to save on cost.

The warmth you feel can also be exacerbated due to heat transfer from the engine. However, heat from the engine is not that quite significant compared to the heat produced by the brakes.

Yup front wheel drive po sya.

From what I've seen here and from a couple of fb groups, it's nothing to worry about, pero ipapacheck ko na din come 1K PMS for peace of mind.

^Padagdagan mo ng grasa yung wheel bearing baka kulang ang nailagay

Mas madami inikot ng gulong mo kesa sa tinapak mo sa preno..hindi ba?
