Brake imbalance MOT warning

[allh2k]

Hello

Had it 3 yr ago they must have missed it a yr later then it's back again last November.

I changed the brake fluid last year (used the ezeebleed kit) and have just changed the disks everything seems fine piston went back and nothing was sticking / seized

The disks I took off were on when I got the car at 52k and it's now at 139k and I had just warped them after a hard brake on the mway

I didn't clean the new disks (I know) and I used my old pads (I know) so the pads (fairly new) were top heavy they have now full covered the drivers side but I still have a cm no contact on the passenger side ( 1000 miles covered)

I'm going to get new pads today as the lip on the old disks had cut very deep into the pads and I dont want alot of lip on the new disks

Anyways my question is wtf is imbalancing and how do I stop it?

Basicly imbalancing is when the drivers side pads grab the disc harder than the passenger side, etc.... vica versa so its uneven braking which can be dangerous. New discs and pads all round should solve it unless there problems with your calipers.

imbalancing is where one side or brakes harder than the other. often caused by contaminated pads or something like that. you should ALWAYS change pads when you change discs as the pad beds to the disc

Never had the tracking done (I know) so will try that as well

I just worry that they will do the old plumber gasp and try n rip me off and then I'll worry ... Try and fix something to difficult and worry some more

Ok new pads today and I might try another fluid change just so I know it's all been done at the same time

Sounds like siezed sliders IMO

 

[allh2k]

Can anything be done with the sliders?

 

[cupra_r_ick]

yes, when you change pads, clean them up properly with wire brush, get all teh corrosion off of them then apply a small amount of copper grease along them to help prevent corrosion

 

[Dan1720v]

Make sure it's a minimal amount too. I've seen them packed full of grease, tbh it wasn't sized but was wearing out 1 side of the pads quicker as it couldn't compress the grease lol

 

[cupra_r_ick]

they do tend to wear one side faster because sliding callipers are shite by nature multi piston for the win

 

[Dan1720v]

Yeh this was wearing out the non piston side first lol.

possible air in one side of the master cylinder,

New pads on and pins/ sliders greased they were v dirty

You don't tend to get FS111 calipers seizing on the slides as they are metal pins on rubber bushes.

The pads can jam on the caliper carrier or the piston can stick.
