Brakes: Replaced brakepads and found few broken stuff.

[Hoggy32]

Alright, it was my first time replacing brakepads, I did both front and rear, however.

In the front I noticed how only one slide pin would move.

As you see in the picture, only the upper one moved. Is it because I unbolted the one down, that's why it doesn't move?
Also the rubber sealing had cracked and one of them was gone, should I be worried and get a kit to renew everything?


The rear brake caliper was a pain in the ass, the piston had to be forced and twisted in which I didn't know, I tried with force only and twist only until I checked a video.
However, I noticed how only one side had this part (spring):

And I accidentally removed it and don't know how to fit it back, what does that do and should I buy another one for the other side?
And one side didn't have the black plastic cover of a hole, check this image:
http://i.imgur.com/5r1P6ps.jpg is this necessary, what does it do?


Also, brake fluid is over clutch mark and near max, however the brake takes "full" action when the brake pedal is half way down, anyway I can tighten it so it brakes as soon as I touch the pedal like in newer cars?

Thanks.

Only Phase 2 cars had the spring so the caliper has been replaced at sometime if yours is a Phase1.And one side didn't have the black plastic cover of a hole, check this image:

It is a dust cap for the bleed nipple to stop the nipple corroding and filling up with rust and crud. Yes, it is necessary.Also, brake fluid is over clutch mark and near max, however the brake takes "full" action when the brake pedal is half way down, anyway I can tighten it so it brakes as soon as I touch the pedal like in newer cars?

Welcome to V/S40 maintenance. That was my initiation as well (the front brakes all seized up).

You can buy kits that include the pin and the rubber covers at an aftermarket auto shop.

Be sure to carefully inspect the piston boots on the rears after you've manhandled them for compression. I've cut the rubber by mistake more than once.

Going to purchase 4x of these, http://www.ebay.co.uk/itm/Sale-FRENK...-/112484739275
Are they the same for rear and front axle?


Also, this is a phase 2 car so I have to have the spring for the handbrake lever, however how do you fit these and where can I purchase them?

Also, the front brake pads came with 2x of these:
Didn't know where they would go so I didn't use them, where are they supposed to be?

Hahaha, I cut the rubber of the rear axle calipers piston because it was in the way :S
Well a kit for repairing would be good enough instead of purchasing new ones, right?

Those things in the picture are wear indicators.. when the pads wear down they come in to contact with the disc & make a screeching noise.
They would normally fit on the inner pad at the top, or bottom depending on whether it's front or rear brakes. Probably not all that important if you choose to remove the wheels regularly & keep an eye on pad wear !

Yeah, I found out about it after I posted the image. And yeah your right, not necessary.

You will need to get the sliders out give them a proper clean and lubricate them with silicon or brake grease don't use copper grease, vital for them to work properly, so try to make it a priority.

Good on you getting into the job, need anymore pointers feel free to ask on here, we are all happy to help

I'll order new sliderpins for each caliper, and I've noticed that they are in different lenght. (front and rear). What I want to know is how the spring is installed and where I could purchase another one for the side that's missing.

[Jebus]

This is what it should look like example

Getting them on, and off is a pain in the arse and you can't really but them anywhere, best bet is a scrapyard and pull some off yourself.

Brakeparts.co.uk is a good site to get parts from if you are struggling to find anything(no springs though)

I'm very doubtful that the spring would be missing. Way more likely that you have one phase 1 caliper assy and one phase II assy as suggested by another member. This should be fine as long as everything is in working order.
