Pulsing through brakes

[danlightbulb]

Hi.

I was getting pulsing through the brakes and the front discs were well worn so I changed them last summer, along with cleaning up the calipers and new pads. Seemed to solve it.

However the problem is now back, nearly a year later.

So either something is causing the discs to warp or its another problem which was masked by new discs and pads.

Brake performance seems otherwise ok. Car is a 2003 Honda Accord.

Any ideas please?

So if it is uneven pad deposits causing the issue, what is causing this to happen and how do i solve?

Read lst few paras abpve "Myth 2"
Harder pads, bed them in and then use them, fiercely.
Thereafter "never leave your foot on the brake pedal after you have used the brakes hard."

You could try giving them a good and proper beasting, sometimes helps if brakes have only had gentle use.


If this doesn't work you'll be changing them again, make sure you clean up the hubs well, any corrosion could lead to run-out and odd wear patterns.

ETA. Check the rear discs, they may look okay on a cursory inspection but the inside face is often knackered.

I think that i did bed them in properly after i did the fit and i dont leave my foot on the brake either. ill try some hard stops then.

thanks.

Contrary to what Stoptech say you can get warped discs.

If you give it a moderate rebedding and it doesn’t go away then the two most likely candidates are a dragging caliper or hub runout on a road car. Make sure that the hub mating surface is clean when you fit the next set.

Also, if your front castor control arm bushes are worn it will make your car more sensitive to judder

Might be worth taking the discs off and giving the face of the hubs and inner part of the discs a good going over with a wire brush drill attachment.

Had a similar problem on my car and this solved it, no idea why it took a while to show up.

I've experienced this having properly bedded in brakes/not left foot on brake. Solved it by repeating the bedding in procedure.

Strange issue I ran into was the sliders had word ever so slightly so allowed movement in the caliper causing light braking wobble fine under heavy braking
