Bleeding Brakes

[OfficialiAmNaz]

Hi,

I've changed all my brakes and pads on my 2004 Toyota Corolla T3 (E12).

They feel quite spongy and i really have to put my foot right down to get the car to stop. 

I have pumped my brakes after the brake change and the brake fluid is at the max mark. I have been suggested to bleed my brakes but the question I have is, what sequence do I bleed the brakes.

 

I thought that it is the furthest away from the brake reservoir which in my car is. 

1: Driver side rear

2: Passenger side rear

3: Passenger side front

4: Driver side front

But my friend has said it should be 1, 3, 2, 4

Is he correct? Or am I? Please let me know.

Thank you.

The sequence according the the Haynes manual is, in order -

Nearside Front, Offside Front,  Nearside Rear, Offside Rear

You said  " my brakes and pads ", do you mean you have changed the Discs and Pads or just the pads ?

If renewing the discs, did you clean the protective oil coating off.

When replacing both it generally should give good braking straight away, but may need a little bedding in.

If you have just replaced the Pads, then it will take a good few miles to bed the pads into the part worn discs, hence garages should always tell you to drive carefully while bedding in.

If only the pads, did you check the disc thickness /condition ?

While checking the pads, did you check /clean/grase the slider pins ?

Bleeding you brakes fully you will need a good 1 ltrs of Dot4 fluid , but it can be an easyish one man job , if you buy a Gunson Brake bleeder Kit, around £20 from many car and diy places like Screwfix & Toolstation.( used one for years, so easy and effective)

Dont forget the clutch uses about 1/3rd of the same master cylinder, so worth bleeding that after the brakes.

Hi

Thank you for getting back to me. Really appreciate for letting me know the sequence.

My mistake, I have changed the Discs and Pads all round. I used brake cleaner to clean the discs too. Used a brush to remove all the brake dust etc from the caliper. 

Unfortunately I didn't check the slider pins. 

I will look into the bleeding kit, actually in my way to screw fix.

[oldcodger]

Do check all the slider pins as if they seize then you cannot get even braking/wear.

Generally they can be removed and cleaned up ok, but if the rust is too heavy or the rubber end is swollen or damaged then new may be needed.

Make a note of which hole /slider pin has the rubber end, one has,  one does not.

I tend you remove mine once a year and lube them with rubber safe  Red Grease, available in small quantities on eBay or some car spares shops keep little sachets.

You will have what feels like poor brakes as you have replaced all the brakes. They will need time to brake and depending on what brakes you have they will have difference isntructions on how to bed.

Bleeding will only help if they were poor before the change. Although it's always good to keep the fluids new.

There isn't a sequence on recent cars, just do whatever way your are most comfortable. I personally start at drivers wheel to empty out the reservoir as much as possible before continuing.

I have bled the brakes and it feels better then before. Not as good as I imagined it will be but better then before.

The new brake pads and disc aren't making a screeching noise as I believe they have bedded in now after a few miles of driving carefully.

I think the next step will be changing all my slider pins and grease them up. I plan to paint the Calipers so it will be a good time to change it then.

Thank you all for you help and advice. Really helped me out massively.

Also attached a picture of the old brake fluid.

Sure looks mucky - any idea when it was last changed , the book says 20k or not longer than 2 years.

2 man job or used the Gunsons kit ?

Without seeing, it might not be necessary to replace all the slider pins, didn't on mine but that was some years earlier and only found 2 seized which cleaned up ok.

If the calipers cannot slide , then you are not going to get correct contact with the outer pad, were your old pads worn to noticably  different thickness on each caliper ?

Found you could just clean the calipers and hand paint then with Hammerite Smooth, trouble is they soon get covered in brake dust, but you sound young enough to clean them every week

I have no idea when it was last changed. It's actually my sisters car and she was complaining about her brakes, so I had a look and saw that they were wearing thin.

I used a none returning valve bleeding kit for bikes and my brother to press on the peddles each time I open and closed it. 

I plan to have a look at the sliders and change them when i paint the Calipers.

I have a friend who works at Euro Car Parts and gave me 50% off on all brakes disc, pads and fluids so I got my sister to change it all to take advantage of the discount. So I do spend a lot of time work on my own Corolla and others to learn more things.

I plan to do a big brake conversation, lowering springs etc on my Corolla. Yes, I am young driver (I don't know how you figured that out? Haha) and its my first car, so I'm trying to make it memorable.

Those alloys look good against the dark grey paintwork, could do with something better myself , still got the originals which are starting to flake.

Not sure about the 4 tail pipes though !   - what engine have you got in there !!

Got the 1.6 in mine and with its lowish gearing it gives me all the poke I need, partic when I red line it in 3rd now and then to clear out the cobwebs

Plenty of posts in the forum about coil overs /lowering / modding etc, plus the Tsport guys do lots of similar things.

Me, only upgrades,  the front Speakers and put some reversing sensors on, not really go faster items, but I am almost walking stick brigade

Don't forget such work needs insurance approval, Ardrian Flux also frequents the forum, an insurer who does cover such work from the serious owner.

Thanks, going to refurb them soon and maybe go gloss black.

I wasn't going to go with the dual pipes but I saw a picture on the forum and I really liked the look of it, so I went with it.

I've got a 1.6 too. I plan to keep this car for a very long time, so I'm looking into a Turbo. Not much about Turbo's on the forum.

Thanks you for the help and super fast replies.
