Brake disc callipers

... I just drilled a hole in a block of wood ( a bit of 3" fence post ) with a holesaw.

It's probably better to use a spade or twist drill. A hole saw would block up to frequently... Ooops, off topic...

I have plenty of time and a set of very sharp wood chisels.    2" diameter spade or twist drills hard to use in a hand drill    Also drill from both sides of wood ( although 2" thick wood would have been better ).  You need to leave top part of bottle sticking out to monitor the level of fluid.

Now look what you've started.

He said atleast 200 miles ive got to do in order to handbrakework normal and rear brakeswork normal. The foot brake goes down 4-5 inches but not completely down. Previous a little touch of brake would be sufficient to stop the car and it was rock solid the brake was.

Here is the Youtube link to my issue with handbrakes. Now, I must say this so you understand the situation correctly as I'm now wonder if my little or no knowledge of diagnosis is correct or not. I might even being silly on such diagnosis. Here are the 2 scenarios anyway.

A- When stopped the car by using the foot brakes and facing downhill or uphill I pull the hand brakes on whilst the gear lever is on N position and the car doesn't move! Which is good!

B- Enging is on and the gear is on N position whilst you're using the foot brakes to hold the car rolling facing down hill or up hill. I take the foot brake off tovlet the car rolls down hill or up hill and I then lift the hand brakes on but the car is still rolling with very little or no resistant at all from the hand brakes. Is it normal

I've contacted the guy who did the repair and he said I should drive more and the handbrake will get back to normal afterwards.

What did he say about the foot brake? 40 miles of normal driving should be more than enough to bed in a brand new set of discs and pads, even rear ones, and as the front brakes do most of the stopping, it shouldn't affect braking noticeably. The handbrake has nothing to do with the footbrake pedal travel.

How far down can you push the brake pedal? If it's near the floor and feels spongey, you need to take care as you may have reduced stopping power from all the brakes, including the front.

It's not always easy to diagnose remotely, but this doesn't sound at all normal. If the foot brake is as poor as you say, it needs attending to ASAP. I would also check the brake fluid level in the reservoir, make sure you aren't losing it anywhere.

Glad you got the video working. That is about as good as my handbrake is when rolling down a hill.

[mj1sjc]

So, is that normal then? Why it doesn't roll over on my scenario 1 as above but only on the scenario-2?

But why this never happened before I changing the brake pads and the discs?

It may go against the grain on the forum, it is like a splinter group, oops where are the Savlon and plasters ?

Whoever# did the work is useless, has made a mistake and refuses to acknowledge it.

The problem is potentially dangerous .
Get if fixed. ASAP

# and there is one rude  word to describe him.

I was trying to be polite earlier, but I agree. If you are experiencing a difference in the foot brake which doesn't feel right, this could be a potentially serious matter and they should not be fobbing you off, without at least looking at it.

The handbrake is neither here nor there, it may well improve as the new parts 'bed in'... though new discs and pads should not take long at all. It's a different matter if you only change the pads, it can take a while for them to fully bed in to the old discs.

I tend to agree with the last few posts.
It really doesn't sound right to me and I'd certainly be reviewing the work, at the very least another bleed and resetting of the handbrake cable adjustment. If the pedal felt reasonably solid before then it should be similar after the work, no reason why it should be a lot softer.
Yes pads/discs do take a little time to fully bed in properly, but they should work pretty effectively straight out of the box, and saying they need 200+ miles to work properly is just fobbing you off.

I have just changed the rear pads on my 2012 Jazz.
Before replacing each wheel I tried the foot and hand brakes about 3-4 times  (to ensure the rear pistons which had been manually retracted had been reset to normal.
When I drove off, the foot and hand brakes felt as they were before changing pads: that is like a new car.

Which is how a competent mechanic should do it.

(Not that I am claiming any great competence being an amateur)

Thank you so much for all your inputs!
I shall now re- look at this and chase him to sort it out. I had paid him £50 cash on changing both rear discs, pads and rear left caliper...

One last question please. I've done few emergency brakings to test the performances of my new rear brakes whilst driving around 30mph. I then felt some cranking noise plus i also felt some vibration to go with it on the foot brake when applying the emergency braking foot brake pedal. Is it all normal? Is this what you called  ABS system or something?

If the ABS was triggered with an emergency stop, then it is normal to feel pulsing through the brake pedal.
