MR2 Roadster Owners Club

I have now been let down three times for maintenance work and parts so its time to start again.

I have all the parts I need apart from two rear break calipers, who would you recommend ? I am leaning towards TCB.

Or brakes International.
Budweg calipers

Any thoughts on these ?

Are brake parts and brakes International the same company?

Looks like it.

I think they may be?

Having seen remanufactured sets of calipers and the issues with them because either they have grease in them that contaminates the brake fluid or the seals are not OEM quality because when they are trying to cut costs they will be inferior and you can feel it in the pedal from my experience on a different car and some of the MR cars I have test driven. I do not know if they remachine the cores when they remanufacture them and by doing so compromising on the tolerances but I do not think they will be as good as factory originals.
 Rebuilding the caliper may not work out as well either. The best option I have always seen is buying a good used set from a wrecker that has a good return policy. 

Around a year ago after much consideration I bought new calipers branded nk  that are a Danish Company. I paid iirc £150 for the pair with a 5 year warranty.
I did contact the company/ distributor and asked if OK to paint them, as I was renovating the fronts myself. The answer was that Imwould invalidate the warranty if I painted them. I painted the fronts silver to match the new rears.
The calioer piston was set  was set correctly to operate the rear brake and they hand brake worked first time.
I bought them on line, can't recall where. Autodoc and Buycarparts Ofer the brand but do not have them in stock at this time.

They all seem much of a muchness so I think I will give Brakeparts a go, thanks.

If you are being let down by someone to fit them, I would recommend making an appointment at Mrtwos in Willenhall, he knows what he is doing and is happy to fit parts you provide.

I changed my mind at the last minute and went with advantageautoparts, normally I would not choose by price but having spoke to a couple of people and reading Anon post I thought bu**er it give them a go.

pros:

• Only £127 for the pair
  No surcharge
  I keep the ones on my car which are hopefully OEM and I can perhaps restore them at my leisure.
  At my age if I am still driving my 2 in 10 years and all I need is new calipers to be able to drive it I will be ecstatic :)

cons:
Don't know (yet !!!!)

Thanks but now that my brake disc is getting warm, pad seizing on ? I need local.

Feeing up the pads in the carrier is easy enough.  So is lubing the sliders with Ceratec grease.  That will almost always cure a sticky pad.

So far so good arrived in less than 48 hours after ordering.

Still £127 in this link ?

Diff age cars? 5 or 6 speed?

The price seems to jump at checkout, clearly states £127 but rises when I go to checkout, mines a 2001 so same model no issue there. Have emailed them to findout whats happening.

Just ordered discs and pads from Halfords a much better price than Eurocarparts - Halfords £59 discs and pads for rear axle.

Norman

@normanh

£59 good going that.

Pagid as well

Norman

Good choice.
That protective coating holds up very well.

 :)  :) Cardiff price the same at £59 does seem a good price without shopping around 8)

The seized up nearside rear caliper replaced and all seems good.

We had a problem with the "good" offside one as the M6 bolt that fits the carrier to the caliper was seized and would not come free even after heating it up and the mechanic was a little concerned that if he snapped it the car would be stranded so we left it as is for now.

I need one of those M8 bolts, Andrew spec best option ? edit: I have a couple of the M6 bolts in my spares draw so not needed.

Has a "bonus" into the cost the braking system gets flushed through and replaced with new fluid :)

Late update.

Well all was not good as the disc got very hot by the time I got home so I assume the brake pads were binding, I adjusted the hand brake to its lowest position in case that was the problem but no still getting hot when driven a couple of miles or more.

Got in touch with a Toyota/MR2 guy who said he could sort it, three times he let me down, last week being the latest let down, jeeese this is hard work ::)  ::)

So I decided nothing for it but to tackle it myself ( I have been missing my run outs :'(  :'(  :'( ), pushed for time because of the weather (no garage) and my wifes mother hospitalized and we have been visiting every day.

This morning got it jacked up and this evening after hospital visiting removed the caliper.

Things I noticed:
The two M12 bolts were VERY tight and dry.
The split in the pad, could I super glue the crack ? kidding !!! :)
It looks like a clip missing, I havent lost it, could this be why the pad split ? could this be why it was seizing causing the disk to get hot ?
I will replace the carrier with one of my restored ones.

I have never had a brake pad crack like that in the past on other cars.

Jeeeeeeeese..................

The pad most likely cracked due to the heat. This is why bedding in pads are important to temper them but in this case the temps were so high it gave way.  Sometimes it is a manufacturing defect as in my case where a front TRD pad cracked.

@TheTigerUK
I'm having nearly as much trouble posting on here lately as you are with your brakes !
Whoever replaced the caliper did not clean and lube the pad carrier.  The missing clip has allowed the pad to move and has broken as a consequence.
Not good practice and certainly not a professional job.
Although you have just had the pads replaced it is best practice to replace as a pair and at both ends of the axle. I doubt single pads are sold anyway!
From where you are now I suggest you employ a mobile mechanic, not necessarily a " specialist and have new pads and clips fitted and lubed together with your refurbed carriers.

I have had absolutely no issues with the Advantage Calipers now been fitted a couple of weeks and about 300 miles done - new Pagid Pads and Discs fitted at the same time by my mechanic son. Never seen a pad break like that as its been said they cant have been fitted correctly.

The mechanic talked a good job but at the time I was not impressed with him for a few reasons but hey ho :(

I will obviously be fitting a full set of pads when I can get them, looked at Halfords and MrBen, Euro were quite expensive and out of interest I will check with MrT.

I suspect that the nipple on the back of the pad was not located in the slot on the piston crown, making the pad rock from side to side when you braked. (Hence the radiused wear pattern and obvious overheating.) It would also explain why you couldn't get the handbrake to adjust.

Better check the other side!

Pagid pads off Ebay will be fine.

On reflection Tiger I think you should consider having that caliper checked as its very likely that the piston has been subjected to very high temperatures judging by the colour of the carrier. More so than that of track events leading to a compromise in the rubber seals. Be safe please and have the other side checked out as well. Just words of wisdom here.

Norman

All now seems good, fitted the new pads and carrier, took the 2 for three trips and stopping every 3 or 4 miles to check the disc for heat, non just the norm you would expect and after each trip I removed the wheel just to check all was fine and I now have a good working handbrake :)

Really good news.

Give me a shout when your ready. I'll pop over and help you take the HT off. Well into BST now.
Now brakes sorted all systems go.

Excellent news, well done that man ;D

Thanks Jane, you know me, hear to help.  ;)  ;D

Good to read you sorted it Tigah. Have fun!

Do I understand that the new pads and carriers were fitted by @TheTigerUK ?
Well done!
