Brake problems (help)

[silvermarty172]

Hi my brakes seem to be playing up , they can be fine then all of a sudden you put your foot down then try to slow down and the peddle goes solid feeling like its wobbling slightly . It comes back afterwards and is fine again .
ive taken it to the garage and basically there saying there not sure if its servo? It's gonna cost a fortune and they can't be sure it will solve it.. Any ideas ppl ? I've tried pumping peddle then starting the car and the peddle drops down as normal. Also this happened after having my rear disks and pads changed. Thanks

If they were non genuine disks, the abs ring might be too narrow and you are getting a iffy signal.

 

[silvermarty172]

They were just mintex disks , is that a common thing to happen then?

 

[Tony Hunter]

Yes, or you have a cracked abs ring. Or they have forgotten to put the spacer washer behind the disc, which a lot of places do.

 

[Tony Hunter]

Take it back and get them to check it properly, would only take 1/2 hour. Your rear abs ring should be 7.5mm wide

 

[silvermarty172]

Ok thanks for your help I'll call them now and see what they say. Cheers

 

[Tony Hunter]

Let us know how you get on.

Tthey say they have checked everything and its all ok =\ just seems strange it was fine before the brakes were done . Looks like ill have to let them do the servo and hope its ok .

Take it somewhere else for a second opinion or have a look yourself?

Did you watch them check it?

 

[silvermarty172]

No didn't watch them . I think ill get my cousin to take a look , he's quite handy with cars unlike me

 

[silvermarty172]

They said everything's fine all pipes, discs etc , so they say the only thing they can think of is servo

 

[Chrisgti6]

They don't have a clue what they are doing. Take it elsewhere.

 

[silvermarty172]

Will do . Thanks for your help ppl

 

[silvermarty172]

Sorry to bother you again .So you would be fairly sure it's not servo that's gone and its something to do with the brakes that have been put on ? Cheers

 

[Tony Hunter]

Sounds like it, but it's hard to tell on the net. If you were closer, I'd have come and had a look for you. It can't be much, just got to know what to look for.

I don't like the sound of your garage tbh, most unlikely to be servo (but I could be wrong).

Hope you get it sorted.

What disc's did they put on? cheap ones I bet.

 

[silvermarty172]

They were just mintex discs and pads . I will leave servo for now and get my cousin to go through bit by bit . Thanks a lot for your help

I've got this exact issue after putting mintex discs on last night. Did you get this solved??

Hi all,
I had this problem the other day! Really gave me a scare after picking it up from a garage after some work,
i supplied some rear discs pads abs rings and bearings ect, mintex from eBay.
well after being told my servo is not working abs pump is not working, I have an air leak I found out that the abs rings on the discs have 48 teeth and threw the abs sensors out!
I tapped the rings of bought some 44 tooth rings chucked them In the oven little bit of lube and tapped the back on.
hope this works for you aswell

 

[Andy93]

Yep changed mine over from the std discs last night and all is well. Mintex are f*cking incompetent!

Lots of problems with not using genuine discs on here, not worth saving a few £s to get branded ones, crap wheel bearings etc to.

Sod's law I did a search and didn't see anything bad about Mintex. Ironically I had the option of Brembos without ABS rings or Mintex with rings from G172 and chose the Mintex as it would be 'easier' lesson learnt!

Just to add, George's service was great. If only Mintex put the correct rings on the discs.

 

[steve!pax]

Glad you got that sorted!!! I will never buy mintex brakes again. It's really dangerous I didn't realise I had no brakes until I came to a junction!

 

[Andy93]

Same here, was on the handbrake like a madman!
