Emergency Stop - now binding!

[Cymru1]

Anyone have any ideas on the following:-

70+ mph slowing for a roundabout, when some w***er who did not have any indicators caused me to "jam on" quite hard. Anyhow, a couple of miles down the road I could have sworn the Tranny van in front of me had it's handbrake on by the smell of burning pads (I had no noticable loss of speed / acceleration!)

However seems it was my pads; my rear calipers are now binding - badly!

Front disks warm, rears to hot to touch. (standard S2 brakes)


Any ideas what could bring it on this quickly? I can understand a rusty caliper/collapsed hose, warping, etc on one side over a period of time. But both sides at the same time?

(I can rock/push the car back and forth no problem with one hand on an alloy "spoke" and cant hear or feel any binding/sticking either when disks are either hot or cold)

The ABS system is split front to back in the S2 so this could be something to do with it. I wonder if there is still some pressure on the rear half somehow?

Do you have any warning lights on the dash or autocheck? Have you tried pulling the fuse for the ABS controller?

Cheers,

Steve.

sticky handbrake, damaged pads and/or discs (they may well be now)

im pretty sure pressure to the back would leave a soggy brake pedal.

I would guess sticky calipers and/or handbrake cable.

Jack up the car and pop the wheel off, you should be able to rotate the disc by hand if everything is working ok, if not investigate if it is the caliper or the handbrake cable itself. Caliper slide pins can seize up as can the handbrake mechanism.

Also make sure the bit the pad slides on the carrier are smooth as they corrode up, quick wire brush and possible file of the edge of the pad backing plate if required.

my guess is that your guide pin seals have seen better days. No matter how bad a state they're in the hydraulic pressure will allow the brake to engage. Problem could be that the brake is stuck engaged after your emergency braking.

As above block the front wheels from turning, release the handbrake, jack the rear and see how the wheels are for free movement. HTH

seals may be worn and making the piston slide on an angle, making it not retract.

if S2 calipers are handbrake on caliper and not shoes in disk setup then try pushing the arm on the caliper back, will help diagnosis hopefuly
