SCARY Moment

[banther]

:S

So last night on the drive back from Birmingham to Bristol the car developed a grinding noise under braking. Pads are due to be changed anyway, so I put it down to that.

Upon returning home, whacked the car into reverse and it felt like something was grinding along the floor. Checked on it this morning and it was fine so drove it the 4 miles to work.

Getting to work involves me reversing into a bay spot, the grinding on the floor returned, put my foot down for the brakes and the pedal fully compressed with ease with absolutely no braking. A few pumps and braking slowly returned.

Im worried to drive it home, anyone know what this is?

​Thanks in advance

Check under the car to make sure non of the brake lines have snapped. If so the could explain the grinding and no brake pressure.

Yeah mate.
​I need to have a proper look after work... and if they have?

 

[Dan@SJM]

Check your pads, make sure they're still there...

 

[banther]

Check your pads, make sure they're still there...

Ordered some new ones mate.... need to talk to you about fitting them as well!!!

​WOuld that explain the sudden loss of brake pedal pressure... but then it returned?

 

[Emblem]

Maybe its the pad's or pad moving in the cailper, had this before... gets so low it slides about.. When you put it into reverse it makes the pad's jump out...

​Right need to get this sorted asap then. Is trhis the grinding noise in reverse as well I take it?

 

[Gavin.]

Don't take this as me being an arse mate but every answer you get on here will be a guess. You need to get it somewhere for them to have a look.

Yeah going to run it somewhere after work. Just a concerning moment!

 

[Dan@SJM]

I reckon one of the pads has fallen out. Probably at the back.

 

[Jaff.]

I don't understand why you'd keep driving a car that has a potential brake issue when you know the brake system required work done on it...?

Well it requires work done in as much as Fred @BTM fitted pads and discs at the back which were 40% worn (just to get me on my way as the rear bearings had failed) and advised that I start looking at getting new pads and discs fitted at the front. Which I have done and work is being carried out in a week.

I'm not so stupid as to drive around a dangerous car - why would I??!

As far as I was concerned it was something on the checklist to do - and its booked in.

Obviously, something may have been missed or something unforeseen has happened - either way, the situation is being addressed.

Thank you for your care and attention.

 

[banther]

Yeah - Fred fitted me with some to keep me going until I get them done with new pads etc.

​I will be getting this done with you - Ill PM you for price etc.

 

[bmh.01]

Rear pads do have a perchant for falling out when extremely low.

 

[Fred@BTM]

I'll be interested to know what this is!

 

[The Fatty]

+1, this explains why you had to pump the brakes again to bring the cylinder in contact with the disc (else you wouldn't have pressure).

One of my rear pads fell out whilst on a black mountain run. Made a dreadful noise and virtually killed a wheel with rust dust! lol.

[Thomaspaddock]

this is hard to read, my brakes seem to be grinding, doesnt straight away though it seems to be when im around 4-5mph

​Sucks doesnt it

 

[banther]

so the plot has thickened.

Took the car to the local garage to check up.... The chap confirmed that all brake pads were present and correct and had legal wear left. Upon returning to the car to sheepishly trundle it over there the grinding noise was still there but now the pedal seems very firm.

The brake lines are all still attached as well.

After the garage I limped it home... Only for the exact same thing as this.morning happen getting home.

The car won't be driven now until it goes to a specialist.... On a trailer, of course

 

[Gavin.]

Master cylinder issue?

 

[welshname]

Please tell me you've got the cap on the brake fluid reservoir?

 

[banther]

Please tell me you've got the cap on the brake fluid reservoir?

ha yes.

Don't worry. Its not moving now until it goes to a specialist. If its bad... Watch this space for 172 cup for breaking!

 

[banther]

Thread ressurection;

So, for some reason, decided to drive the clio up and down the drive (about a mile long) to try to see what the problem is. The grinding noise has got worse after none use with the car violently vibrating when i brought it to a full stop. Brakes also squeek now.

All the pads are still there and the discs don't have any cracks or look warped at all.

Also, their is now a squeeking noise all the time even when not on the brakes.

I'm an absolute (ABSOLUTE) noob when it to this. Any suggestions so i can drove it to a specialist rather than get it towed?

Please

 

[sbridgey]

So, what happens if you stop with the handbrake? Does it still make a vibration?

 

[The Fatty]

have you considered jacking up the car and spinning the wheels by hand?

 

[banther]

no I haven't. Silly me

So, what happens if you stop with the handbrake? Does it still make a vibration?

Yes I have and no ut doesn't. Presume this means front brakes?

 

[sbridgey]

I would guess so yes. Did you get the front brakes checked over?

 

[_WILL_]

If its brakes tow it. If a child ran out in front of you are you confident your brakes are 100%. From what you have said they are not. Tow it.

i would say one of a few things:

something stuck between pad and disc.
fucked calliper, prob rear.
loose wheel ( unlikely but easy to check )

brakes squeaking is not an issue really, especially if it has been sat for a while. Just a bit annoying. If a speasialist is taking brakes apart ask tell them and they can stick a little copper grease on them to shut them up.

 

[MRBILLYUK]

Well if it's not making a noise when you stop using the handbrake that's got to rule out the back brakes , so you're gonna have to check out your front brakes , starting with your pads . The squealing could be metal on metal , your brake pad backing plate on your disc . Look through the wheels and see if you can see any heavy scoring marks on the discs .

 

[banther]

I would guess so yes. Did you get the front brakes checked over?

visual inspection yes. It was presumed it was rear brakes at the time for some reason.

obviously im not so stupid as to take a car.on the road with fucked brakes.


Its not a light squeeking its a loud grinding then violent shudders when it comes to a complete stop. I don't have the tools at home i.e. Axle stands, socket wrenches et to take apart the caliper itself and see if anything is stuck in there.

ill have a look tomorrow before work mate. It does sound like metal on metal. Quite scary really. I bought a full set.of discs and pads from g172 which should be here tomorrow its just getting.someone.here to fit them for me. Eurgh.

Thanks for.your help so far all.

I'll keep you posted

P.s. Could it be brake fluid.or.something.silly like.that?

 

[plymcl172]

I am not driving the car....... oh wait maybe I will...... your first stop should have been a garage end of

 

[banther]

Read the whole thread first.

I took the car out on my own private road today just to see if incoupd diagnose the fault myself before getting the pads and discs changed. A piece.of gravel stuck in there or something.

I did take it to a garage.

 

[MRBILLYUK]

visual inspection yes. It was presumed it was rear brakes at the time for some reason.

It won't be your brake fluid if it's a metal on metal sound . Like i said before , it sounds like there's no friction material left on at least one of the front pads , maybe more ..... ? If you could jack it up and spin the wheel you'll hear it grind if it is . Keep us posted . Oh , and take it to a different garge than the last one you took it to . Any decent mechanic would have checked out all 4 wheels / brakes tbh mate before sending you away with an unresolved problem .

Yep jack it up for sure, only takes a 30mins to check both sides using the Renault jack if you have no other. If you have the sound there all the time, it should be pretty obvious where its coming from if you spin the wheel by hand. Just remember, when doing the fronts make sure the handbrake is on tight and the car is on level ground, take it out of gear as you will need to spin the wheel easily. If you end up checking the rear, make sure the car is in gear (1 or reverse) and again on level ground.

Also you wont need a specialist to work on your brakes, any good garage will be able to do that no problems. Specialists are preferred for advanced things like timing belt ect. this might make it easier to get it to a closer garage

Where abouts in Bristol are you based?

Yeah its going to Dan @ SJM for all that at the weekend.

​Just would prefer to drive it rather than have it towed!!

 

[Matt@codered]

Is the brake pedal vibrating with the 'grinding' noise....have the abs rings been checked to see if one is cracked?

 

[banther]

I cant say I remeber the brake pedal vibrating.

Its a cup so doesnt have abs..... does this matter?

​Can anyone in Bristol help me fit the new pads and discs? Can repay in interpretive dance.

Ah. Didn't know it was a cup.....:S When the garage checked the pads were the wheel bearings ok?
