I've discovered i have at least one seized rear calliper piston ;-/ probably because the car gets very little use i suppose. Heard a nasty rattling last time i was out and discovered the brake dust cover had broken away from it's mounts. While I was in there i discovered the seized piston. Just been to my local trusted car spares shop and they don't do them, does this mean genuine Skoda or is there a decent alternative anyone can recommend? Thanks.

How good are you with your hands and how much money do you want to spend...

 

I've often stripped a calliper to component parts, cleaned and reassembled without any parts being replaced.

I rebuilt mine several times but never overcame the problem of the auto-adjuster not working, it was not clear which way round the seals went and I think someone had been there before me and failed.

 

Eventually I bought a pair of new Chinese calipers for next to nothing from Maxspeedingrods (google them) who sell on ebay and also direct, they worked perfectly.

 

I am very obstinate and made many attempts to repair the calipers with seal kits.

 

But as MicMac says, if its just a seized piston then usually its just elbow grease required.

Hi prefer not to spend anymore than really necessary but as it's brakes kind of keen to try and get it right first time. I'm reasonably competent with spanners was hoping to rebuild the calliper especially after a few YouTube videos doesn't seem that complicated have done a few on motorcycles. Unfortunately the rubber dust boot doesn't look great so I'm thinking that should be replaced. 

Depends a bit how you want to go about it.

 

My rear calipers seized up on the octavia when it was sat for a while, and I just needed the car back on the road quick, so I bought a couple from https://www.partsinmotion.co.uk really good company to deal with, prices are fair (unlike ECP and GSF online where they wind the prices up then have a sale most of the time which brings it down to an OK-ish price). If you put your car details in the comments, they double check everything's right before they send the order. 

 

https://www.biggred.co.uk/ will refurbish your calipers really well and send them back to you. They take a few days, but do such a nice job, you probably end up with something that's better than a new caliper. 

 

If you've got the time and tools, DIYing a rebuild isn't too bad. Always put a new pot in though, whether it needs it a not and take your time getting everything spotless. The thing is, your parts bill can go a fair way towards the cost of either a caliper, or getting someone else to rebuild it. 

 

If you're up for taking a chance on a quick bodge. You can often free a rear caliper up reasonably well with some release spray and giving the pot a turn with a set of plumbers grips before putting the windback on. It might not work, and it probably will seize again, but it might get you going for now.

OK just to let you guys know thanks for all the info brakes now sorted had to press gang a mate in to help but all done and all seems good. Think it's likely going up for sale soon as I live in the area where that idiot London mayor is planning to expand his ULEZ area to cover and euro 4 diesel not got a chance of compliance but hey ho I'll save that for another day. 🙄🙄🤔
