Brake/Wheel rubbing

parisian62 · Post by **parisian62** » Mon Jul 06, 2009 5:33 pm

Hi Everyone,

I've noticed that in one spot the front passenger wheel is rubbing. It has stock rims and tyres.

I've taken the drum off and there is plenty of brake pad. Drum doesnt looked scored.

My neighbour has suggested that the tapered bearing might be worn or loose and to tighten the castellated nut one notch might do the trick.

Any suggestions? Brake pads need adjusting?

regards
Stewart

Sounds like he's talking about the stub axle and wheel bearing, I've got them on my cars and I don't own a Skoda

OK sorry...what Trev said...stub axle and wheel bearing....soooo...would tightening the wheel bearing be any use...?

Stewart, what is the wheel actually rubbing on ?

Any pictures could also help to narrow it down ?

Stewart, I wouldn't just tighten the wheel bearing, it may need a grease first, Trev

Stewart, where exactly is the rubbing you describe??

A pic would help diagnose the problem.

Hi Finny and Terry,

My bad description in the first post. Its not the actual tyre/rim/wheel thats rubbing...it seems to be coming from the brakes/bearing...I've jacked the FB up and as you spin the wheel you can hear in one spot as the wheel spins a rubbing noise. My gut feeling is what Tim first suggested - either the shoes are out of alignment, or need adjusting or drums are out of round.

I've never adjusted or 'fixed' brakes so any hints, tips, traps for young players or advice will be greatly received...

Stewart, my front right does the same thing. It's so bad that if I let the car roll down my sloped driveway, it will actually stop when it gets to that point without me even touching the brake pedal . I've put it dowm to uneven drums and a bit of over adjustment last time the brakes were adjusted.

The more I drive it though, it seems to go away

OK. I guess because it was a new 'noise' that I hadn't heard before and because it was brakes it was getting to me.

many thanks.

Check that the 2 shoe retaining pins are still in place.
And that the brake shoes aren't worn down to the metal or separating.
Out of round drum or foreign matter in the brake shoe.
Loose or worn wheel bearing is another possibility, but more likely brakes.

If you back off the brake adjustment several turns and spin the wheels.
If the noise goes away, it's drum or brake shoes.

If its a kind of soft "rubbing" type noise then its most likely what others have said, an out of round brake drum causing the brake lining to "grab" in one position when you rotate the wheel and then free up somewhat once it turns past the binding section.

Not a great problem but in bad cases the pedal can pulsate when brakes are applied as the brake lining is pushed in and out by the out of round drum this is transferred back to the pedal as a pulse you can feel.And can become a pain in the arse after a while everytime you apply the brakes.

My old bomb has out of round rear drums and pedal pulsates,has been like it since before Yamba Nats, I'll have them machined on a brake machine lathe when its due for new rear linings soon.

Not uncommon and happens to cars still even today ( warped discs ).

Drum may also be bent as can happen sometimes if brakes have been stuck on in the cars prehistory and someone has tryed too overzealously to pry the drum off and has bent the drum mount face and/or bent the backing plate although if bent enough this causes more of a grinding noise rather than a rubbing noise.

Wheel bearings if very loose or ready to collapse due to wear can also create a grinding/scrubbing type noise.

If internal brake components are loose or broken it usually results in a scrubbing or grinding noise so it probably wouldn't hurt to have a look inside there to see if everything looks to be in order.
