Help please - Brakes pull to the left

[Mike Terry]

Whilst on a Sunday blat the car started to pull to the left during braking. I noticed also that the FOS wheel twitched over to the left. The FOS wheel has now been confirmed as the cause by tests being done while the car is up on axel stands. Harsh sudden braking did not produce the effect.

 

I suspect the cause is a sticking piston on one side of the brake disc that does work when more force is applied.

 

I have standard front discs so nothing fancy. Can anyone tell me if it is possible to strip down the disc brake piston assembly? If so are any specialist tools required and any new gaskets. Failing that, what Haines manual would they be in?

When I rebuilt my car I removed the pistons and fitted new seals which I got from HERE. The parts are Triumph Spitfire HERE and it was very easy to do, the pistons come out without having to split the caliper and no special tools are required.

I hope Mrs T wasn't with you Mike. That really isn't going to endear her to the car.

 

As Guy says, they are very easy to refurbish and I would tend to do both sides at the same time if it were me.

Thanks

 

A great ReHaB response *thumbup*.

 

I've got to get this done for Stoneleigh and I trust both you boys are coming (7:30 start and not Dick the day before start time).

I have freed up a sticky caliper by removing the pads and pushing the piston right back into the caliper(dont put force on the disc use a small engineers clamp or a proper caliper resetting tool) Then operate the brakes to move the caliper back out ( back to its normal position plus perhaps a mm or so) repeat a couple of time. Mine caliper occasionally does this if left a couple of weeks without use. moving the piston a few times usually does the trick

[Mike Terry]

Thanks Bob i'll give it a go

if you are pushing the piston into the caliper and then back out, give it a good clean first so you don't introduce more dirt into it.

 

Also look for suspension bush wear. I have had similarsymptoms with a worn lower spherical bush.

And if you've topped up the fluid reservoir make sure it doesn't overflow!
